U.S. officials have long seen their country as a Pacific power, with troops and arsenals at a handful of bases in the region since just after World War II.

But the Biden administration says that is no longer good enough to foil what it sees as the greatest threat to the democratic island of Taiwan — a Chinese invasion that could succeed within days.

Since the start of his administration, President Joe Biden has undertaken a strategy to expand American military access to bases in allied nations across the Asia-Pacific region and to deploy a range of new weapons systems there. He has also said the U.S. military would defend Taiwan against a Chinese invasion.
