Do you know anyone in Russia who wouldn't be advocating the exact same thing as him if the situations were reversed? If the US military landed on the Russian shores tomorrow, would you advocate your countrymen lay down their arms and let them simply have the country, since if you refused you would prompt the launching of nukes and go out in a "blaze of glory"? This reeks of hypocrisy, to be honest. Of the Russian posters here, I think you're the only who would even consider arguing for Russian surrender, and I don't even think you would go that far - but you argue that this is the stance UR should take.
If US armed forces were in our territory, calmly and relatively peacefully taking over parts of Russia, then one of two things would happen. A) I would be conscripted into the military, unfitness be damned, or B) I would watch quietly from the sidelines as all the benefits of a unified east-west economy roll in unopposed. Well, at least unopposed
by me. There's plenty of idiots that would prefer to go down swinging, to fight for some kind of ideal or custom. See: Honor Before Reason. Russians being crafty people I foresee a lot of Killdozer situations. But I really would prefer it if no fighting happened. If nukes started to get thrown around, pretty much everyone would lose, one way or another. If bombers start taking passes at our car factory, with the kind of accuracy those butterfingers pilots have they'd be hitting the residential areas too "by accident", and I rather like this place with as few extra craters as possible. The roads are bad as it is. War is really bad, mkay?
I honestly try to never wish upon another that which I would not have happen to myself. While the US taking over Russia would wreck all kinds of things in the day-to-day, unless it happens in a violent manner I do not see anything outright wrong with it. A lot of things would have to happen for that event to come to pass - and if our government is weak enough to let something like that happen, if they are weak enough to allow the US to be so bold as to simply march in and start taking stuff, then I would rather side with the stronger government. I would technically become a US citizen, if it
really is like Russia did with Crimea. We'd probably finally get the pavements in the driveways around here fixed
permanently. There are benefits to a change of leadership sometimes. So no, I would do exactly as you describe. I would advocate that our troops stay where they are and only put up a modicum of resistance to the takeover, giving any remaining politicians and diplomats a chance to do their silly thing and attempt to sort the mess out.
If Abrams tanks start putting holes in the facade of my favorite grocery store however, well... I have an SUV and some rocketry experience. I'm also a big fan of the Katyusha. ^_^
