You might disagree with the ruling on moral grounds but it changes everything for the person in question. I am just pinpointing a harsh reality.
That is his personal opinion (and subjective).
In order to understand how US is able to exert its influence over much of the world, you need to concentrate on its economic clout and contributions to the globalization phenomenon. No country is immune to American pressures, no matter what.
Three recent examples:-
Russia - subjected to heavy sanctions; economy tanking [drop from 6th spot to 13th spot in a span of few years]
China - subjected to political pressures in regards to North Korea; China feeling the heat and doing the needful
Venezuela - subjected to economic pressures; economy collapsed in 2015 in spite of heavy Chinese investment
It is impossible to show US the middle finger in the manner you think.
