"How else do you explain the two helicopters being shot down so quickly?"
I know it's not a popular opinion, but the "government" in Kiev admitted over the past few weeks that numerous armories had been taken over in the Eastern Ukraine.
Why is it any surprise that a helicopter is shot down when those armories had to have supplies of both MANPADS and anti-tank missiles? It's not like you have to be some sort of uber brain to operate the new ones, you follow the aircraft, wait for the lock signal, and pull the trigger.
That's exactly why countries worry about terrorists getting them and shooting down airliners, they're easy to operate and very effective.
Current regime in Kiev can not be called "legitimate government" by any stretch of imagination. "Our man Yats" and his Nazi thugs from the Right Sector are junta who establish themselves as country rulers in a coup AFTER an an agreement was brokered between Germany, Poland and Russia to hold elections in May and elect new Ukrainian government.
These are verifiable facts. One can have right to personal opinion but not the right to personal facts.
