When the Islamacists took over a city here in the south, the military had just been denied weapons from the US under Obama so he had to get them from China and Russia..

When I was last in the Philippines in 65 they were about to throw us out. They are a great people and I don't blame him for getting tough on the dope dealers and muzzies survival requires it, but the groveling before China is not a good choice. I can understand why they might not like cozying up to the Japanese after the way they were treated in WW II.
I loved liberty there, always friendly and safe there during Marcos's day.
