I want to save time for those who are new to this conversation — the problem is not that Ukraine has to “give up” something to Russia “for peace.”

The problem is that no matter what Ukraine “gives up” now — be it Crimea, or Donbas, or Kherson, or Zaporizhia, or Odesa, or Kharkiv or anything — it will not give any sort of “peace” and will only strengthen Russia in its goal of defeating and eradicating Ukraine as a nation and incorporating its territory into its empire.

The rest is just idle talk.

I've spent so many years of my life in this very building… hundreds of my memories lead me right back here, to this very alley 💔

[Defense of Ukraine @DefenceU]

Sumy. A terrorist strike by russia against a peaceful Ukrainian city.

This morning, russia launched a ballistic missile attack on the center of Sumy. Civilians were killed and injured. Sincere condolences to the families of those who became victims of this strike.

It happened on Palm Sunday, as people were on their way to church. The strike on civilians was deliberate and insidious. This was no accident — it was terror.

The world must respond. Ukrainian lives depend on the determination of our allies.

We urgently need additional air defense. At the same time, work must continue on real and effective security guarantees for Ukraine and our citizens.

Strong, united actions can stop the russian aggressor.

[Volodymyr Zelenskyy / Володимир Зеленський @ZelenskyyUa]

A Russian missile struck an ordinary city, directly hitting a street in an area with residential buildings. Preliminary reports suggest it was a ballistic missile strike. As of now, 14 fatalities have been confirmed, including six children. My condolences to their families and loved ones.

The rescue operation is ongoing, at least five residential buildings have been damaged.

Russian strikes occur every day. People die every day. There is only one reason why this continues: Russia doesn't want a ceasefire, and we see it. The whole world sees it. Each missile, every attack drone proves that Russia seeks only war. And only the world's pressure on Russia, all efforts to strengthen Ukraine, our air defense, and our forces—can determine when the war will end.

The United States, Europe, and the rest of the world have the capacity to force Russia to abandon terror and war. And this must be ensured—peace is needed.

[Illia Ponomarenko 🇺🇦 @IAPonomarenko]

This is what Russia does to Ukraine on a daily basis.

This is Kryvyi Rih just tonight, Zelensky's hometown.

A Russian Iskander missile, a cluster load, fired just into the middle of a densely populated residential area, next to a playground for kids.

At least 14 killed, as of now, including at least 6 kids.

Lots of pictures of mutilated dead bodies... people burned alive in a car.

This is what Russia does every single day to Ukraine.

Keep going, shall we?

Q: “In terms of the Signal chat controversy…is the DOJ involved at this point?”

Bondi: “…We're not going to comment any further on that. If you want to talk about classified information, talk about what was at Hillary Clinton's home that she was trying to BleachBit.”

[Oleksii Kachaiev 🇺🇦 @kachayev]

The transformation of the US into russia has been successfully completed. Would you like to discover what’s new?

Leavitt: “If this story proves anything, it proves that Democrats and their propagandists in the mainstream media know how to fabricate, orchestrate, and disseminate a misinformation campaign quite well. And there’s arguably no one in the media who loves manufacturing and pushing hoaxes more than Jeffrey Goldberg.”

A few more hints to a new reality.

[CALL TO ACTIVISM @CalltoActivism]

Greene: “What country are you from?”

Reporter: “The UK.”

Greene: “We don’t give a crap about your opinion…why don’t you go back to your country.“

Marge Greene is a fucking embarrassment to our country.

We shall endure this as well

[Oleksii Kachaiev 🇺🇦 @kachayev]

“He doesn’t represent all of us.” He does. You gave him power. His choices will change millions of lives, yours too. Like it or not, that’s how it works. Pass it on.

“In four years, it’ll be back to normal.” It won’t. Nothing will be back. That’s just your ignorance talking.

[Oleksii Kachaiev 🇺🇦 @kachayev]

Words matter. Say "Ukraine’s war", and you ask Ukraine to end it. Say "russia’s invasion", and you know what must be done. Do you?

[Oleksii Kachaiev 🇺🇦 @kachayev]

@CalltoActivism When putin says “russia has significantly larger rare earth reserves than Ukraine” he means literally “when we own Ukraine, we will have their reserves to sell. Works for trump who couldn’t care less.

[Oleksii Kachaiev 🇺🇦 @kachayev]

They (trump’s admin) don’t care if you believe Ukraine invaded russia. That’s not the point. It’s just a loyalty test. The real lie is simpler: “Ukraine is about to lose”. They need you to believe it exactly because it’s not (not even close). To kill hope and determination.

[Oleksii Kachaiev 🇺🇦 @kachayev]

@mimrocker Why would they invite a TASS reporter into the room if they weren’t planning to put on a show for putin?

[Oleksii Kachaiev 🇺🇦 @kachayev]

The performance was (obviously) staged. Yet the truth remains: Ukraine stands *unbroken*. We will not bow - to russia, to the US, to anyone. Zelenskyy stood firm. The country stood firm. History will record the shame of those who abandoned truth. We made our choice. So did they.

[Illia Ponomarenko 🇺🇦 @IAPonomarenko]

Disgracefully rude behavior from JD Vance, and I can't believe that the Vice President of the United States is acting this way in the Oval Office of the White House in Washington, D.C.

What is the point of this forced antagonism and this contrived arrogance toward the leader of a country that is fighting for its survival and freedom—a country that is friendly to America?

Zelensky came as a friend and speaks with respect to America as a friend and partner.

[Oleksii Kachaiev 🇺🇦 @kachayev]

Watching thousands of MAGA accounts frantically delete tweets calling Zelenskyy a dictator would be amusing — if it weren’t so bleak. Ministry of Truth? Warping reality on command is the essence of fascism. Seeing people obey and rationalize it without question is even darker.

[Oleksii Kachaiev 🇺🇦 @kachayev]

The nation’s right to self-determination is not granted by Trump, nor can it be revoked by him. It is inherent. The arrogance of Americans who believe otherwise is staggering. Ukraine will fight on, regardless of the illusions others entertain.

[WarMonitor🇺🇦🇬🇧 @WarMonitor3]

Trump says that Ukraine will have to sign the mineral deal "For a right to fight on".

What a ridiculous statement to make, Ukraine will fight on regardless of your administration.

[Timothy Snyder @TimothyDSnyder]

It should be astonishing, though it’s not, that the American negotiators want to begin from the premise that Russia was right and that Ukraine is not sovereign. Accepting the lies of the aggressor isn’t just unethical, it’s also unstrategic. Agreeing with Russia that a war of aggression leads to the end of Ukrainian sovereignty is not just morally but factually wrong — it is a complete misreading of what happened these last three years, as Ukrainians won crucial battles, took back territory, and proved their existence by any conceivable metric. Any peace will have to begin from legal and political reality. For America at this point in the war to -help- Russia undo Ukrainian sovereignty is not just injustice but a provocation to a much broader war.

[Volodymyr Zelenskyy / Володимир Зеленський @ZelenskyyUa]

Three years of resistance. Three years of gratitude. Three years of absolute heroism of Ukrainians. I am proud of Ukraine! I thank everyone who defends and supports it. Everyone who works for Ukraine. And may the memory of all those who gave their lives for our state and people be eternal. 🇺🇦🇺🇦🇺🇦

[Oleksii Kachaiev 🇺🇦 @kachayev]

@mimrocker I think trump’s administration is just not get used to hear “no”. They are still to learn that executive orders don’t work outside the US.

[Oleksii Kachaiev 🇺🇦 @kachayev]

Trump: Sign the deal immediately and get nothing, or you gonna get nothing at all!!!

Zelenskyy: I’m not signing anything.

Trump: *confused*

Trump: *confused and angry*

⚡ Zelenskyy on the minerals agreements draft with the US: "We should not recognize grants as debts."

"I want a dialog with President Trump. I do not want to sign something that the next 10 generations of Ukrainians will have to repay."
