This is the Prelude to War, can't you see that?

When Iran starts acting like a fool, like the WH hopes it will he can involve troops before he is out of the office. If Bush knows a Republican will take the next office he may just stop at airstrikes.

Or else giving them the rope to hang themselves ?

Have to extend the option of a diplomatic resolution always, but if Iran does not take it then it removes all doubt doesn't it ?
