@revelette1,
Obama's deal meant the nuclear issue had been kicked into the long grass, giving Iran time to engage with the rest of the world. One people have a taste of peace and normality they want it to continue. If you keep people in harsh conditions they develop a siege mentality, like Londoners during the Blitz.
This will only help the hardliners and make Iran more likely to seek nuclear weapons. They kept the Jongs safe in N Korea while Saddam Hussein was deposed, sentenced to death and executed.
Christendom and the Islamic world have at odds since the first crusade in 1095, and as far as Moslems are concerned, America is very much part of that conflict. Not being a country until 1776 makes no difference whatsoever.
