Both of the above are the 64K dollar questions . Who knows what new weapons they (Iran) have yet to unveil ?
Sure skill and technology goes a long way but lucky shots ain't bad either .
Who knows the measure of their (Russia & China) resolve when it comes to stopping our meddling and imperialistic ways .
Their respective militaries are starting to work together more than they used to . I'm bettin that's a "clue" .
I hope you were being a bit sarcastic when you typed this. The US hasn't gobbled up and assimilated whole countries lately. Russian held most of Eastern Europe until they couldn't afford the armies to keep their power and they're flexing their muscles again. And China invaded and assimilated Tibet and is harassing shipping in the South China Sea. The US has no monopoly on "meddling" in the world.
