Golez: According to this article, the F-35 can stop and contain China:
"President Donald Trump is concerned about the costs associated with the F-35 Joint Strike Fighter. But the F-35 is arguably crucial to two Trump Administration priorities. While working to control costs on the aircraft, the new administration should also consider what this jet can do to help achieve their broader policy goals:
1) Contain China: Japan, South Korea and Australia are buying the F-35. Exporting it to Taiwan and India, and basing U.S. squadrons in the Philippines as well, would envelop the Chinese military in a decisive manner. The encircling aircraft would see without being seen, causing allied airpower to dominate any conflict in the Western Pacific.
2) Encourage allies to "pull their weight": Our allies want these planes badly. Exporting the F-35 is the easiest way to multilaterally enable them to share defense burdens. Japan and South Korea, for example, will be far less reliant on the U.S. for security once they receive this powerful aircraft."
