F#$k me, not another multi versus single snow job. Its all a cost, benefit analysis, simple.
We can keep moaning about it, but the F35 is what we are going to get, its the only thing with any advanced capability on offer. I personally don't like it, and the whole "all your eggs in one basket" scenario, but thats the cards we have.
And to be perfectly honest, no matter what people may think of the idea, all our countries are basically modeling our defense around being in bed with the US.
Another words, we most likely won't be going up against any significant adversary without uncle Sam being there. Hence our force structure is mainly set up to integrate or complement that scenario. There are some obvious local differences, but from the big picture, thats it.
