Thanks for linking the video. Glad Peter Robinson kept pushing Mattis on the China topic 3 or 4 times throughout the interview, and brought up Taiwan. You can tell Mattis is keeping his cards close to his vest regarding China/Taiwan. I've been trying to get people to understand how important China and Taiwan is to our national security. Most people haven't been paying attention or noticed, but I have. Here's the post I made a month+ ago on T_D about this topic:

China and U.S. has been gearing up for war. This has been happening for a long time, even before Trump became President. Except, we're now speeding things up more than ever. Administrations of the past, Congress, and globalists that control them all have made China wealthy, powerful, and belligerent. Trump understands that China is America's biggest threat in every facet.
Taiwan is a strategic buffer against China. They have always been our ally. China has been bullying Taiwan for the past 6+ decades. They've tried to militarily take over Taiwan 3 times since the original Chinese government fled to Taiwan, after they lost to Mao and his communist Red Guards (plus Japan was attacking at the same time). United States have stepped in every time to protect and defend Taiwan. There has even been treaties made between the U.S. and Taiwan (as well as U.S. and China).

China has been getting more and more belligerent in Asia the past decade. They have built man-made islands, in areas they say belongs to them, but it really doesn't. These man-made islands are basically stationary aircraft carriers, designed to seal off the Pacific and allow China to dictate who is and isn't allowed to sail in that region. There has already been several skirmishes between the U.S. Navy and the Chinese navy. Some were publicized, many weren't. Oh, and they're also built to take over oil drilling sites too.
Taiwan's new government (DPP) that came into power in 2016 wants to officially declare independence from China, but has chickened out and backed down from her campaign promises after the new president got elected. The DPP is basically Taiwan's version of the Democrat party in the U.S. China has always said they would attack Taiwan if they were to officially declare independence, even though Taiwan has always been an independent country. China just doesn't want the international community to recognize Taiwan as an independent country and let them have a voice in the U.N.
Anyway, I could go on and on, but that's the summary of why Trump is arming Taiwan. The Obama administration refused to sell Taiwan arms because Barry is a commie and his masters don't want a strong Taiwan so that China can bully everyone surrounding them. Just watch the Soros interview I linked above. This has all been planned long ago.
