Phlippines and China in South China Sea

The US recently pledged a US patrol craft to the Vietnamese navy. Was it because China had reclaimed over 2000 acres of land by 2015 in the South China Sea? Some of the ASEAN countries don’t wish to make a choice between China and the US, except the Philippines and Vietnam. The Chinese had also constructed a 3Km runway for handling fighter jets. The Chinese are merely catching up with rivals who have also built airfields and other infrastructure there on their own islets and reefs. Obama administration has no consensus answer to stop Chinese muscle-flexing. Why did the US invite a CNN crew on board a surveillance flight over islands claimed by China, and broadcasted the radio challenges by Chinese military on the ground? US aircraft’s crew rebuffed eight warnings during its flight, saying that was international airspace. US had violated the Chinese sovereignty. Why are US spy planes routinely patrolling China’s coast? Should US back Vietnam and the Philippines at any price? Vietnam and the Philippines have classified Beijing’s interests in the South China Sea as maritime and territorial ambitions, which is not true. Beijing was only protecting what was under Chinese rule for more than 2000 years. Under international law, a nation controls 12 nautical miles around islands and coasts. For the issues in the South China Sea, everyone has a different idea of where he stands between China and US. Lucrative arms business must be the objective of those who are fanning for wars in the South China Sea? Is China militarizing, or is it wrong for China to upgrade its armed forces? The Chinese needed to have better armed forces after the Mao-era. Beijing is beefing up its hold over hotly disputed islands, so why don’t you send your armed forces to attack China now? Why is the US pressuring China by publicizing a surveillance flight over contested islands in the South China Sea? Chinese dredging activity provoked a diplomatic protest from Manila in February 2015. If China is wrong, why are the Philippines not able to declare war on China now to solve this pressing problem, now that USA is fully interested to start a war with China? Can we be the technological and entrepreneurial powerhouse?
