What if its England or France that become the vacuum they are former power houses...whats wrong with that? they are our allies and friends. Iran will never ever ever become more of a power than either of those countries...yes not even bigger than the french!
Sure the US has done a ton of good, we defeated facism, invented the automobile(take that god, we dont need your horse) helped poor and suffering people all over the world....except we cant help our own poor so that is a fault I think.
We tried to stop communism but we didnt. Dont count us winning the cold war as the end of communism, its called the People Republic of China (who happens to be our best friend) Vietnam and Iraq 2.0 reaffirmed something thats been around for a long ass time....people will change when they themselves want to change....Force only makes them do it out of fear. Fear will make people lash out negatively, like a caged dog.
Who are we to project our values all over the world.... Do you want a democrat projecting their values to your republican children or vice versa. Do you as a Christian want a Muslim to project his faith and values on you....most likely not. Yes we have done good, but if someone doesnt agree with us we have to listen why and what can we do to find a common ground. You cant have everything your way.
And if you view people as your enemy nothing will ever get done because enemy=bad bad=must be stopped by all means=I dont listen till you stop.....wow where have I heard that before....oh yeah Bush 2.0
You are vastly understating the good the US has done in this world...Ask Japan and Europe (both rebuilt by us) how badly that experiment has been? Ask the South Koreans the same question.
As for Iran, they are strong enough to project power on to their neighbors, and that would not be a good thing.
It's not a matter of stepping aside and letting someone we agree with or like carry the load...It's way bigger than that. And if you think China and Russia, especially Russia, wouldn't like to project more influence and power in the world than you are just naive.
And believe it or not, some people see diplomacy and good will as weakness and appeasement.
