Biden basically gave the Saudi's the finger for killing a journalist. They gave us the finger back and spent a bunch of money in other countries instead of the USA.
He removed the terrorist designation from the Houthi and took sanctions off Iran and they rewarded our kindness by attacking our ships.
Trump bombed the hell out of the Houthi and repaired our relationships with the Saudis.
Trump gave a speech over in the middle east and said he doesn't believe in keeping permanent enemies.
This is definitely one of those situations where there simply are clear differences in Foreign policy.
