It seems like you really looking forward for a ground invasion to remove the regime. I can totally understand that.
I feel the reluctant on the U.S. side is that U.S. have fought a number of these drawn out invasions with large spending and human casualties. In the end, they left these country in chaos and stagnation, arguably not much better than before.
Do you feel if there is a ground invasion of iran, will it be a different story?
Plus, how do you feel about U.S. bombing iranian universities; do you feel it is necessary?
(sorry it feels a bit like I am forcing your answers towards a direction. I am genuinely curious in what you think.
