House lawmakers visiting Taiwan this week are warning that a Chinese invasion of the island could likely lead to a direct conflict between the U.S. and Beijing.

China's two-day military exercises last week surrounded Taiwan, demonstrating what a blockade or invasion could look like.

As China surrounded Taiwan with a massive naval and air armada for a large-scale rehearsal for an attack, Adm. Jon Leonard was being briefed at the Hawaii headquarters of the U.S. Indo-Pacific Command.
