Why do you assume the aliens want to set up a one-world government?

I do not. Nor did I write that.

Perhaps if I rephrase...

The UNITED NATIONS will use the (created) threat of an alien invasion to implement a One World Government.

Gotcha. And I agree that the UN will use every opportunity available to create a one-world government...with the UN in control of that government.
