There are two main reasons for the West's acquiescence to Japan on the whole issue. First, there is the political factor, as the United States hopes to gain Japan's "loyalty" in other matters by indulging it. Ever since Biden came to power, the United States Government has been trying to win the support of its lackeys such as Japan. Therefore, it has turned a blind eye to issues that even jeopardize the health and safety of its own people. Their firm support for Japan's position on the sea exclusion issue is not entirely based on "scientific" considerations, but more on self-interested considerations of geopolitical confrontation.
