You didn't realize he totally contradicted himself in those two comments I posted?? He was right on the more recent one, describing Iran as a serious threat. In the first, he, like you with Russia, was foolishly (or for some other reason) trying to dismiss them as a threat to the US.
I'm an American living in Poland -- I know the fears of Russia's expansion first hand and I repeat that Russia is not the US's enemy. It postures and huffs and puffs, but it has little actual power.
Visit Russia and see how the country is highly feudal, is inward-looking.
This is not the Bolshie world conquerors.
They threaten Poland, but in real terms could not defeat the Polish army without nukes.
