Yes but they have QUAD. China don't have an equal for the QUADYou underestimate China's friends, especially in the region. At the same time, you grossly overestimate NATO.
Why is USA so desperately trying to get India to aggressively posture against China and tie down Chinese forces on the LAC? The reason is quite simply that NATO has no teeth outside of Europe and North America. This isn't a simple stand off against the Warsaw Pact where a solid front line was established, sucking the life out of USSR's European strategy. NATO cannot and doesn't wish to assist USA in its Asian-Pacific misadventure.
