He has also said that Iran cannot gain nuclear weaponry. consistently for 10 years, even in his announcement speech in 2014 or 15 as i recall. it was a huge point as to why he cancelled Obama's nuclear deal w/ Iran, and was a campaign issue in both elections (but overshadowed by other issues in 2024).
Trump has, very consistently, been very adversarial on the topic of nuclear proliferation for decades.
His point on forever wars was ALWAYS that the US just didn't go in and kill everyone like we should have (remember "just kill them and their families" in the 2016 GOP primary debates?). He has never been isolationist, but rather just anti military quagmire. in all his military excursions he has favored overwhelming force, fast timelines and decapitation strikes against leadership (Soleimani, Maduro, Khamenei).
His use of the military is much more in line with the US of the 19th century/ early 20th century. Quick operations, mass destruction of enemy forces and punitive military expeditions (See Indian wars, Banana wars, war of 1898 and The Mexican punitive invasion among others).
