Of course there was a military plan for this since months, but that does not mean that plan was surely to be executed. (A likely option I assume)

What I find worrying is the standard tactic seems to be to do negotiations, let the other side assume there is hope for a other solution - and then attack hard all of a sudden. Already the second time. It might be effective short term, but it erodes what is left of trust negotiating with the US.
