The problem with that logic is America is not that strong anymore. Without the use of Turkey as a staging base we would be significantly weakened in the region. Remember at the start of the invasion of Iraq when the US was enraged because Turkey would not all the US to use their country as a base for launching their northern ground invasion. Also, Turkey is a Nato ally which puts the US in a position to choose a side that they can not afford to do at this point. Of course the US could go nuclear, but there would be nothing left to fight for if it ever got to that point.
