According to Radio Liberty (RL), U.S. Senator John McCain has explained that the escalation of the situation in the Donbas is such that Russia is testing the administration of U.S. President Donald Trump.
"The Russians are killing Ukrainians daily. They are killing them. I believe that the situation is going to get worse, because …. this is a time of testing for the Trump administration," said McCain during a panel speech on February 17 at the annual Munich Security Conference.
Since the situation in combat zone in the Donbas began deteriorating, John McCain has urged Trump to provide Ukraine with lethal weapons at least twice.
In late January, McCain criticized Trump for statements regarding the potential lifting of sanctions against Russia.
