You got down voted because some folks are either ignorant of wider geopolitics, or of certain inclination and don't want to hear the inconvenient truth.

I am originally from Philippines which hosted a major US military base. Despite the protests, the Americans did not leave until a major volcanic eruption nearby prompted them to do so in the early 90s. I am anti-imperialists as much as the next guy and the overseas American military presence is an on-the-face sign of imperialism, but the fact of the matter is that many countries literally "free ride" under American protective umbrella. It saves the country money and deter rivals. That being said, in hindsight the Americans should not have left, as China has now started claiming an entire sea region and bullying Filipino and Vietnamese fishermen. China has also literally set up a military base within 200 nautical miles of Philippine exclusive economic zone without permission, which the international court deemed to be illegal.

Many Filipinos changed their tune from "go home Yankees" to "Yankees come back! You should have stayed" because hindsight is 20/20. Right now, American soldiers are dripping back slowly to the Philippines since the Chinese military is still squatting.
