Is Vlad trustworthy?
Compared to what—Obama? He’s fickle, and he’s nuts.
Now the Kurds are being attacked both by ISIS and the Turks. Aligning with the Russians and Syrians reduces threats to the Kurds in Syria, gives them an ally against ISIS, and may make the Turks reconsider bombing raids into Syria and Iraq against the PKK.
Vlad isn’t trustworthy, but he has the power. You may be dealing with the devil, but you do that when the devil is holding all the trump cards.
