Since Iraq shifted into a house-to-house guerrilla war, the Navy and Air Force have largely been out of the game. If the war broadens, they're back in the mix. A carrier group or two, backed up by B2s out of Diego Garcia, have a way of making an impression.
How long would it take a column of tanks to go from Iran to the closest large concentration US troops? Could we bring massive air power in time? Just wondering, hope for the best, plan for the worst, hope we have a plan for a general mideast war cause one might just break out.
