While I agree and of course we must fix our own house the threat of a nuclear Iran or them having a bomb and the West and America allowing them to have one and the danger that may come from that is as important or even more so in that sense.
We have an opportunity to have a world where Iran doesn't pose a nuclear threat here and now and for future generations or just sit back and see the opportunity fade away..... Same with Iranian people now too and people in the region with that regime, they have an opportunity to kick out the bums and an opportunity at freedom vs oppression thats been going on for decades and decades.....
Why continue the BS and kick the can down the road in that sense when we have an opportunity and they have an opportunity.....
Its not guaranteed and it's not perfect but it's worth the risk IMO for better tomorrow for future generations and something that is worth the fight IMO.
