That’s not weakness. Look at Ukraine, Iran, they get wrecked, what victory would look like? Life is short, the goal must be not war but seek a peaceful settlement.
As for going to war, that’s always a dead-end. Singapore former gov chief was asked on US military power on Vietnam. He is Chinese, he knows Vietnam, to win against Vietnam the US must be smarter, their feet be faster than the Vietnamese. Otherwise you see, he smiles, because he knows the outcome.
Yes, at the end Millions of US soldiers, almost the entire US navy, land army, Air Force were fighting until exhaustion, were unable to win the war and withdrew.
