Seventy year old technology and Non proliferation of the same is a fools errand. Take a look at a 1940 Auto.......Now really, just because some brilliant Jewish fellows in Stagg fieldhouse at the University of Chicago came up with the theoretical and practical use of the atom, did you really think that this technology can be secreted and controlled because we got it first? Non proliferation is a goal of all nations. Its foundation is not that folks will not have the ability to make bombs, but that the proliferation of this technology is harmful to everybody. Why is the State of Israel allowed to develop a nuclear weapon, and then when Iran does the same they become evil?
Iran is dangerous because they sponsor terrorism. Please name one terrorist act sponsored by Iran which has happened in America or Western Europe. There are none. However, Lebanon had a high percentage of Shia and when Israel invaded Lebanon, Iran backed terrorist attacks on Israel. The United Nations condemned the invasion, and although the PLO was predominantly sunni, almost 300k shia civilians were adversely impacted by the invasion. It was the second Invasion of Lebanon which Hezbolla grew and became the sworn enemy of Israel. It was at this time the infamous https://en.wikipedia.org/wiki/Sabra_and_Shatila_massacre
took place, and created a Iran/Israel dynamic which in the world view and the United Nation's view, Israel was the bad guy. The American press however, framed this as PLO terrorism vs Israel, but it was much more as Israel like today was destroying neighboring nation states and a Christian pro Israeli government was supported by Israel in Lebanon. These invasions, the Lebanon civil war, and repeated invasions created an environment in Lebanon where Shia were experiencing high civilian deaths. In this context, the rush to attack Iran with our fingerprints all over regime change in the fifties, and horrible abuses of the Iranian people under our puppet the shah, and Israel's less than stellar behavior in Lebanon has heightened the dialogue between Israel and Iran.....diplomacy is the only answer. We could control the air and take out their military in less than a month, but occupation.......we would lose the occupation just like we lost the occupation in Iraq.....context Bob....context.
