The difference is, that with the Russians, their promises to retaliate are believable. The US is a paper tiger.
Real men lead Chechen and Russia. We have Urkel and a 72 year old drunk that never served a day in uniform but likes to make bold threats about what the US will do to the enemy, when we all know they will do nothing. We are the laughing stock of the world with democrats in charge of US foreign policy.
