Here is what is apparently a Chinese reporter planting a Chinese flag on some bit of disputed land in the massive South China Sea territory. Here is a Chinese hacker "planting" a Chinese flag on the website of the Philippines News Agency. Here are tit-for-tat pictures of people burning China's flag and people burning the flag of the Philippines. I would suggest to the Philippines that neighbors that have land disputes with China often end up in unhappy situations.
Also did you know that in 1951 we signed the "Mutual Defense Treaty Between the Republic of the Philippines and the United States of America"? It's true! Hillary Clinton was just over there a few months ago reaffirming it and stuff! Oh, hooray.
