I'm not saying these arguments are wrong or invalid, they're all very valid, but current expectations must be realized.
At this point there is no going into Iran in mass on the ground beyond guerilla shit. At this point we would do good keeping Iran out of Israel, and 95% of Americans are like fuck that even, that includes our armed forces. Even that would come down to a multi-decade war worse than Vietnam and Afghanistan combined.
Are we willing to pay that price? Are you past 50 and just knee jerk reacting? I don't want my kids dying in this war for Israel. Our surface navy is COMPLETELY invalidated by hypersonic weapons. This is not the same world as Iraq and Afghanistan wars. Trying to save Israel currently is a logistics and humanitarian nightmare and would come with a massive loss of American life. This would be akin to taking Japan at the end of WW2.
Anyone arguing for that IMHO is psychotic. Focus on our own fucking hemisphere. Q called it. Q made the map. It is what it is.
