I think a Trump win could mean at least soldiers being sent to Gaza and Ukraine being handed over to Putin in the name of "peace", which would fuel the territorial ambitions of other dictators. A lot of Hungarians are still mad about Treaty of Trianon, see Slovaks as a "fake nation created by the Habsburgs/Jews/communists", and this is only my country. China has it's own territorial ambitions, so are most other regimes.
