Reacting to the “loss of China” the United States Congress extended to President Eisenhower open ended authority to defend Taiwan—technically known as the Republic of China on Taiwan—with military force. The resolution came at a time when the United States faced challenges from the People’s Republic in Indochina as well as the Korean peninsula. Effectively, Taiwan sat under the US nuclear umbrella, and the balance of power within the Taiwan Straits would now remain a question of strategic importance to the United States.
Time: Early War
Removed after event: Yes
Generally inconsequential. It is only relevant if the Asia battlegrounds split 3-3, and even then most US players do not bother taking Taiwan early on because of its cost. I will almost always play it without hesitation in the Early War, especially if the US has the China Card.
Occasionally, in the Mid War, if Taiwan is already taken by the US (i.e., to protect against Korean War) and the battlegrounds are indeed split 3-3, then Formosan Resolution can give the US Domination. But I find this somewhat rare — much more likely is that the US ends up cancelling it by playing the China Card before Asia is scored.
Note that unlike Shuttle Diplomacy, this does not go away after Asia is scored, only after the US plays the China Card. It also matters for Final Scoring.
Unless I already have Taiwan for some reason, this is not worth the effort. It’s just too many Ops in the Early War: Taiwan is a costly country and you’d have to give up the 2 Ops from Formosan Resolution too.
Sometimes this can be helpful in a Mid War deadlock. But even then, the tedious process of playing Formosan, controlling Taiwan, and then playing Asia Scoring is usually too slow.
That having been said, this is a second reason to take Taiwan, the first being a defense against Korean War. Usually either of those reasons on their own is not enough to take Taiwan, but together, I will probably invest the 3 Ops.
