US could ask tourists for five-year social media history before entry

All sanction’s or regulations that they apply towards us, should be mirrored towards them.

This is something I have heard before, and I understand the logic. However, I am not convinced it is possible or even effective because every country doesn’t have the same leverage, and America is the most powerful country in the world. If most countries in the world wanted to reciprocate, the US could use any leverage they have against them to deter them from doing so. Some European countries have threatened to deny more visas from certain countries if that country didn’t do what they wanted. Basically, whoever is the most powerful will win this stupid game, and innocent people will suffer as a result. Hence, I’m not convinced this is the right solution in the long term. There is also the fact that the EU does the exact same thing to other countries.
