Was it worth invading?
In short no./
Iraq did not pose an imminent danger to the US in terms of terrorism. We had him boxed in, and we could drop bombs on them whenever we wanted. Saddam had a big mouth, but he was impotent.
We never, ever should have gone in there.
The entire WOT was a ruse to encircle Iran.
I hate that so many of my peers have had to go there, two, three or four times. Each time they come back thinking less of the people in command.
The US is the modern Rome. We are not in full decline, but we are sure past our high water mark.
Imho, the invasion upto the point of capturing Saddam was correct. We should have left immediately after, left a note saying don’t tread on us again and marched straight into iran, with the same mission.
An invasion was overkill. Could have easily taken out Saddam with an air strike, Cruise middle or some other standoff weapon.
A covert assassination would also have done the job. Once Saddam and his sons were assassinated, the line of men wanting the job would have been very short.
