Turkish Pres. Erdogan shouldn’t be let off the hook for Turkey’s occupation & colonization of northern #Cyprus, which began #OTD in 1974. Why is there so little outcry about this illegal act? Why does he get a pass? How much longer will this beautiful island nation be divided?

@stevenacook understands how catastrophic the consequences of Turkey’s belligerence in the #Aegean can be. @USAmbGreece does too. Are @SecPompeo & @SecretaryMattis prioritizing keeping Turkey from starting a war within #NATO?#NoJetsforTurkey https://t.co/ou8fqIf2tJ
