The best shot for Intel taking over TSMC is getting the US to start a war with China at Taiwan. Of course it will be a tragedy, but in that case Intel is strategically important to the western world.
The wording is weird. The US cannot start a war over Taiwan, the only way for a war to break out there is for China to invade.
They would probably have a monopoly, and with that, too much control, and so, are liable to become lazy and greedy, which will harm everyone involved.
