He isn't wrong.
Trump is a business man. He wants America to be strong, make money, employ people and essentially stay in business. He doesn't want to waste money and lives in wars. That's why he never got us into a war and set up us pulling out of Afghanistan before he left office. War only profits the wrong people, it doesn't enrich any country or any of the average citizens. War only hurts the middle class and enriches the rich.
Part of being a business man is he is excellent at brokering deals and talking to people and figuring out ways to work out problems. I honestly believe he could at least keep the problem from escalating further. Other nations listen to a strong man with a strong nation behind them. Biden is a weak man with a weakening nation behind him.
