Sorry but there is nothing suspicious with this. The US started helping when russia started invading the Ukrain in 2014. When a democracy fought for their freedom and finally could get rid uf janukivics Tyranny, Russia attact, since Putin has a problem with democratic countries.
Ukraine has every right to defend all its theretories. Give me some points on why the defense of a democratic country is wrong? And what is the problem sending them support in weapons, education and intelligence?
