Well i did not expect that from you. To wish war and destruction on others is disgusting.They celebrated the end of a decade/era of UN sanctions, sanctions which if imposed on Iran would have you without Internet today. Far heavier than the sanctions Iran experienced.
I feel that throughout the years here all the arguments end up to be of no use. It's not like you needed me to explain you this, some thinking could've enabled you to understand beyond what you just wrote. Those that celebrated Saddam's fall would throw a massive party seeing Iran's coons being thrown out of Baghdad.
Point is, Iran is exporting cancer. Soleimani was of no use, boomer poster boy bringing human-wave tactics. His attempts in Tikrit (fully led PMU operation) failed heavily, massive PMU casualties due to his failed tactics. The PMU's input came with a high cost, a major payment in human life. The same thing Iran did in the 80's, nothing genius about it.
I hope America and Iran clash directly.
