the 21,500 number is a simple 15% increase to match the 15% increase in insurgent numbers. It's an inflationary adjustment. The ONLY reasonable expectation is that nothing will change as a result. Simple warfare - you increase your number in proportionate to the increase in the enemy and nothing changes.
This leads the reasonable man to believe Bush wants to maintain the status quo - as that is obviously a status quo number. And the Gates mandate for the next 5 years is 92k men, which is 18k a year. More of the same. Maintenance force levels for 5 years.
So when you say this options is "okay" it means you're okay with the current level of progress - close to zero.
hell yes they do.
what you say makes sense, however, it's all based whether your prediction of "nothing changing" comes true. it doesn't matter how many we send in anyway, what matters is the amount of force the military is allowed to use. in other words, bush could call back the 21,500 send in 2 or 3 bombers, drop a few daisy cutters and it's over. he could send in half of those troops and they could level baghdad. if they were allowed.
so i don't believe bush wants to keep the status-quo, if his statements about no restrictions is true.
of course you would be right if the reinforcement troops were sent in with no changes and having to succumb to the same political correctness. that would be maintaining the status-quo.
