Once in, China immediately challenges the Helms Burton law at the WTO dispute resolution panel so as to end the criminally ridiculous US embargo against Cuba...and wins. The EU becomes incensed, as it had tried and failed in 1996, stymied by US bullying and threats.
Jesse Helms, Dan Burton and Strom Thurmond in their final and only act of sanity call for the US to withdraw from the WTO and then commit suicide on the floor of the Senate, despondant over being outsmarted again by Fidel and his friends.
The US pulls out of the WTO and the system collapses as the US warships around Cuba vanish during a temporary anomaly which enlarges "the Bermuda Triangle".
