President Trump warned that countries are going to “hell” if they embrace the green energy transition and fail to clamp down on irregular migration, in a long and highly combative speech that questioned the purpose of the United Nations during its 80th annual gathering.

Trump followed through on what the White House previewed as “tough talk” to the global body, in a speech that lasted nearly an hour, the longest U.N. address of any U.S. president ever.

“Both the immigration and their suicidal energy ideas will be the death of Western Europe if something is not done immediately,” Trump said, making an argument for closed borders and unfettered energy exploitation.

"Time to end the failed experiment of open borders. End it now. I can tell you — I'm really good at this stuff — your countries are going to hell," he added later.

Trump also hit on many of his favorite domestic themes, touting his deployment of the national guard to Washington, D.C., tax cuts and global tariffs.

Here are five takeaways from Trump’s first U.N. appearance in his second term:

“All they seem to do is write a really strongly worded letter and then never follow that letter up. It's empty words, and empty words don't solve war,” Trump lashed out at the body.
