I cannot think of any country that has consistently committed more horrific acts in the last 150 years than the USA. And they have always been very slow or flat out refused to take any responsibility for any of it, including genocide, the instigation of countless wars and bloody coups aimed at overthrowing a government that did not play nice with us and our corporations, and a rich ongoing tradition of racial segregation (still alive and well in the south and against Native Americans, despite all the laws to the contrary). Yet I refuse to be held accountable for any of this despite spending my entire life in the country. And I certainly don't want anyone else to hold me accountable for it. The bottom line is that horrible corrupt regimes will be living fabulous lives of extravagance, regardless of how much their citizens suffer in poverty. This is true in N Korea, Africa, Latin America, and the USA. You are not hurting anyone with any power or influence by staying away. You are, however, depriving many local merchants and businesses of much needed income. In the end, depriving yourself of an experience because of something you have no influence or control over is going to affect you exponentially more than anyone else.
