Between 1981 and 1986 (and beyond) the good ol' US of A didn't mind illegally selling guns to Iran.
Further, they didn't mind using the profits from the sales to fund the 'Contras' a right wing terrorist group looking to overthrow the Sandanista government in Nicaragua.The fact that by doing this, they were breaking international law didn't bother the Americans.
This whole disgraceful event was led by a corrupt President Reagan. That he pardoned all of the men found guilty of those crimes says a lot about the laws of that country.and many believe he had full knowledge of the criminal actions.
(It is further alleged that the CIA imported tons of Cocaine to fund the guerilla/terrorist army, but that's another story.)
I mention it because it shows they have no regard for international law. No respect for human life. No respect for other countries.
The rest of the world and even the American intelligence community knew in March that Iran did not have the ability nor desire to build a nuclear missile.
200,000 people died in Hirosima and Nagasaki all because America wanted to show the world they were in charge.
Iran may be the enemy but our so called friends are no better.
