Why do you think European and the United States government supported the creation of Israel in the late 1940's?

Explanation:

If you are a cynic, you might believe it was a guilty conscience. The allies did not even attempt to take note of what was happening in Europe.

Of course Germany was very thorough and very clever about how they gathered  their intelligence on how they knew who was Jewish and who was not. They simply sent their computer experts into a country they knew was next to be conquered and examined the voting records of that country.

People in the 30s trusted their governments and declared their religion.

After 1942 the Holocaust began in earnest. I've given you this snippet only to show you how dedicated Anti Semitism was in the early 40s. There were many instances of how the allies could have done something but didn't. They tried to make up for it by giving a part of Palestine after the war.

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
