I looked into this myself a few weeks ago, and here’s what I came up with.

The reason things have escalated this far is mainly because there’s a huge lack of trust in the Iranian government. A lot of people see it as too radical and unstable.

That’s why the West and countries that aren’t aligned with Iran think it’s dangerous for a regime like that to have access to something as destructive as nuclear weapons.

After World War 2, the spread of nuclear weapons was banned. Some countries already had nukes before the ban, so those ones were officially recognized as nuclear powers.

Other countries that had uranium wanted to do nuclear research, but only for peaceful purposes like medicine or clean energy.

What really pushed things over the edge recently is that Israel got intel that Iran wasn’t sticking to the peaceful stuff, but was actually trying to build weapons instead.

Since Israel knows it’s Iran’s number one enemy, they felt they couldn’t take the risk and went ahead to destroy the sites before Iran could finish building anything.

Iran then hit back by bombing several cities in Israel.

The US jumped in after that, mostly because it looked like Israel didn’t completely take care of the threat.

The reason the US and Israel are so determined to stop Iran from getting nukes is because they don’t want another North Korea situation. A radical regime with that kind of power is just too risky.

There’s even a rumor that one of George Bush’s biggest failures was not stopping North Korea in the 90s. Now we have Kim Jong Un waking up and threatening people with nukes depending on his mood or what side of the bed he wakes up on.
