Let me put things another way: you originally made quite a tall claim that the US “if it wants could delete the Houthi leadership” and confronted with my point that in similar conditions not long ago the US failed to “delete” a leadership even though it wanted to, your whole argument is now “it’s not quite the same conditions”.
Of course it’s not the same: it’s a bloody different country.
The thing is, merely me pointing out a situation were the US failed to “delete” a leadership when it wanted to is enough to prove my point (and if you want another example, how about Vietnam) because I was never making the point that the US will fail if it tries, I was making the point that US is not guaranteed to succeed, i.e. I was disproving your original claim and all that it takes to disprove a certaintly of success is to point out 1 situation where the it was a failure.
The entirety of your argument now is about “it might succeed” because Yemen ain’t Afghanistan.
Well, yeah, sure, I agree that it might, but that’s not what you wrote originally: what you wrote originally is that “if it wants it can”, which is a whole different claim from “it can try and maybe it will succeed”.
Whilst Yemen not being Afghanistan means US is not guaranteed to fail to “delete the Houthi leadership” if it tries (and I never claimed it will), Yemen being similar to Afghanistan makes it more likely (IMHO) that the US will fail than if, for example Yemen was like Iraq instead.
All that however is mere decoration to my original disproving of your original post which was done since I pointed out how it once in the recent past wanted to and failed.
