I'd say this is the best way to contain communism and to get China to become a free society for the purposes of joining the LU and getting the trade benefits with it.
We also get to save money on the military since currently the world spends $1.6 trillion on the military a year and china spends about $200 Billion a year. A world united against the communist countries can save $1 trillion a year on the military, still outspend China 2 to 1 and some of that money is used to improve the LU, some of that money can be used as a tax cut.
The constitution for the LU might be below:
If the world unites against the communist countries, we don't have to spend as much on the military per taxpayer and some of that money can go to social programs(liberals are happy), some of it can be used as a tax cut (conservatives are happy), and communism inevitably falls (America is happy).
