Why don't you ask the EU how well making deals with Iran went so far? Hell, why not ask Israel? (they've been making deals with Iran for 47 years and saved their bacon, espeically in the Iran-Iraq war, multiple times. The sad truth is that half the Iranian regime, both the regime itself and the individuals involved owe Israel their lives. Most owe both the Mossad
and the IDF their lives)
Here's how politico describes the EU's relation with the Iranian regime in one article: "Iran continues to hold and execute European Union citizens, using capital punishment for accused spies or dissidents, leading to severe diplomatic tension and EU condemnation of 'hostage diplomacy'"
You think Trump is untrustworthy? When is the last time Trump invited someone for diplomacy ... then had that person executed?
I mean, I get why people make the point that Trump is the worst US president ever to deal with. That's politics, and there's an election coming up... what I don't understand is why people get confused about that still making him 1000x better than a lot of other parties.
