It will be beautiful. A naval force like you have never seen will stream across the Gulf of America to make Mexico great again (we can't go overland, there's a wall there). Troops will work their way down to reconquer the Panama Canal, which Jimmy Carter sold for $1 (a very bad deal, by the way).
But we won't stop there, we'll expand our presence to the north as Denmark gives us Greenland, which will be very good for national security. Once surrounded, Canada will become the 51st state.
The war in Russia will be solved before I take office, and the hostages will come home from the Middle East. We will drill baby drill, and the most beautiful word in the English language -- tariff -- will be the word of the year. The tax every other country will pay us will make us rich, and we'll cut taxes, even bigger than before.
All this will happen in the first week if the Democrats don't get in my way. You'll see.
