How do they do it? Through not revealing everything that goes on in the trade agreements.
What I mean is, the trade agreement involve loans from banks to countries. When the country leaders sign a promise-to-pay note to the banks, they don't realize that the note becomes money, and that this money-note is used to prepay the loan. There is no need to make loan payments that enrich the banks for nothing in return.
According to the law of contracts, there is no full disclosure about this by the banks. This nullifies the contract. That is why Russia, when they figured this out decades ago, stopped following the terms of their agreements with the US. The US broke the agreements ahead of time by not making a full disclosure to Russia. The contracts were essential null and void from the start.
Same with almost all the countries that borrow from the banks.
However, if the country leaders know what's going on with bank loans, they haven't informed the people. They are guilty of treason against their own people.
There is no question that our life is now in the hands of warlords who are distributing deaths everywhere.
