it does not cede any ground. you are operating on the assumption that obama is weak on foreign policy and that he wants the missile shield to be 'done away with', even though it is being maintained by the current action, and has been expanded over the course of his administration.
neither party wants the missile shield issue to go away. neither party wants the current deployment of the missile shield to go away. look at the actual results.
i'm not saying it is immediately likely, but rather that it is possible so long as their foreign affairs remain contained (and this is the best case scenario for the current long-term strategy).Iran has shown previously they will brutally crack down on even the slightest whiff of a protest against them, the possibility of a actual revolution any time soon is fairly unlikely. Not to mention a actual revolution taking place in Iran may be even more dangerous, as they could try to instigate the U.S. or Israel into attacking, or attack a country in a type of "Wag the Dog" scenario to gain patriotic support back at home.
"you can have skirmishes back and forth"? the actual timeline is like: years of sporadic conflict involving increasingly dangerous violence and threats led into months of increasingly deadly skirmishes which led into military buildup and invasion.Except there was no real gradual development, you can have skirmishes back and forth, but Russia decided that it was time to put the hammer down on Georgia, this wasn't something that was a slow build up for years. It went from small skirmishes to outright invasion in nearly the blink of a eye.
you can disagree that this is a gradual development of conflict (though this seems definitionally mistaken), but it really has no bearing on the threat of invasion for western europe or the united states, which is the actual issue at hand. in such cases, the russians make noise but do nothing.
and this "nothing" is the situation, in actual fact, that exists right now between russia and the missile shield deployment! they haven't done anything about it, and they don't have any real reason to do so - noise is helpful domestically, but they are actually looking for enhanced global economic integration, so the threat of russia is out of the question.
