Grift you say? revenge even for minority countries ? Bankrupt already poor economies and reclaiming power by bring chaos into poor economic countries?
Just because you are a poor country, that does not give you the right to abuse a richer one. A lot of the trade deals are terrible, you have no idea what you are talking about. On some things the USA has a tariff of for example 10% while the other country has a rate that it 5 or even 10 times higher for the same category of items. Why should they accept this? Do you know how much aid there are giving to all of these countries? Don't bite the hand that feeds you..
