Iran deal

So Trump officially signed the MOU/deal with Iran. Here’s my problem with it. I always understood that the Iran issue is bipartisan, because of Iran’s radical ideology and nature. There have been many attempts to stop Iran from gaining power, especially it’s nuke capability. In the previous methods, rather then killing the actual snake, which is the powerful regime with a destructive ideology, pushing them off and limiting their abilities. The issue with those methods are, as we witnessed, that Iran is not trust worthy because they value their ideology over their word, and they go any length to gain more power. The US has previously addressed the Iran problem with keeping the benefit of americans, mainly their wallets, as the priority when dealing and negotiating with Iran, but we’ve seen that this was a failure, and Iran managed to grow their biolistic and nuke capability under all the sanctions etc. The longer the regime existed, the bigger and more of a problem they became. Once they grow to nuke capacity, they become a world power and grow from a problem to a dangerous disastrous monster amongst the nations.
The problem with the deal is not only do we not stop them from growth, we allow billions to get funneled into the terrorist regime (which we officially don’t negotiate with) which historically allows them to rebuild their terror anti west ideologies stronger and better then ever before. Aside from the fact that the terms clearly reveal to us, and worse, Iran, that they have real negotiating power and the better side of the deal, it also holds israel under a stricter then before scope when they fight Iran’s direct threat proxies in the region. We practically just reevaluated the big bad monster of terror as a legit organization with rights.
The only real solution to the problem from a practical perspective is weakening all military capability and regime change. When a new regime takes over, although they might not be the best, but they have no military power.

What do you guys think about this?
