Timeline 240 Left Supra 2

This timeline is mentioned in passing in The Cross-Time Kamaitachi (p.5). It is said to be "the one where Joe Biden won in 2020 and most of the Far East, including Japan, is radioactive wasteland."

The unstated implication is (at least to the author) that Timeline 240 Left is "our" timeline, i.e., the author's timeline, the readers' timeline, the timeline where you're reading this wiki article, and Supra 2 is a supra line of that branch where, sometime between 2020 and 2024, China tries to invade Taiwan, our current (p)resident does nothing, and things go pear-shaped, i.e., nuclear. Further implications are that Japan and South Korea reveal nuclear capabilities many of us have long thought they had, and come in on Taiwan's side. Further, author sayeth not, other than hopefully we aren't living in the Supra 2 line of Timeline 240.
