I don't like the long, on-again, off-again venture into Iran, but I'm willing to give him the benefit of the doubt about whether we should be involved. It is true that all of our recent presidents, Republican or Democrat, have made statements about Iran not being allowed to have a nuclear weapon, yet they did nothing about it. Obama sent them pallets of cash, and I don't know for sure whether Biden said anything about it, but I'm sure he wouldn't know either. If our involvement in Iran is necessary, I'd much rather we get it done and get out than drag it out as we are. If you remember, we heard the same rhetoric about North Korea for years.
