Also if they "were just about to have the bomb" then they could develop it and use it after. So there is the conflicting position that they are both insane to use it and but both sane to not escalate the conflict. This is where most pro-war arguments fail the basic logic test in the nuclear bomb era.
that's a fancy retelling of history you got there. MILLIONs died in those wars and less than 100K US troops died. Out of those wars, iraq 1 led to iraq defeat and withdrawal from kuwait. iraq 2 had saddam dragged through the streets and a regime change within 3 weeks, yemen was counterterrorism - there's no regime to topple, in afghanistan the taliban regime was removed for 20 years and only once the troops were withdrawn were they able to crawl back.
the current Iranian regime is over.
One of the key reasons behind why Iraq fell so quickly is that Saddam made all the wrong moves leading up the invasion.
By that point, he had alienated every single potential ally (including Iran) - and virtually all states in the region were supportive of the invasion, regardless of their positions in public.
Not to mention that the invasion of Iraq was ultimately a failure anyways..
It's so funny that you can't see the parallels
Unfortunately, international law means nothing these days, so it might have been a mistake to not establish deterrence sooner.
Regardless, Iran is not going to be as easy to topple as some people might think.
Come back to reality friend, nobody is alienated.
Do you think sitting by and doing nothing will not pose an existential threat to the government by way of constituent discontent?
