Right. But since when was "we could not get approval to do it our way" a valid reason to do away with international law?
Mind you, this is not to say that under certain circumstances, it isn't permissible to say "fuck it", and just do what you have to do. But to me, it would not seem that all possible options had been exhausted before the use of deadly force.
Also, if the images that are emerging from the airbase are anything to go by, the airstrikes seem to have fallen well short of the alleged goal of totally disabling the base. Which, interestingly, might or might not have been the purpose all along, Trump-style. Do something to be able to say you tried, and intentionally fuck up so you don't hurt your friends too much.
