Human Rights Violations and War Crimes
The United States spent tens of millions of dollars on Tomahawk missiles so it could totally fail at destroying a Syrian airport. Supposedly the operation was done in retaliation for the Syrian government using chemical weapons on rebel fighters. You see, under no circumstance will the United States tolerate human rights violations and war crimes! The might of the United States military will be brought to bear against anybody who crosses such a line!
Unless, of course, the human rights violations and war crimes are occurring in a country the United States has no vested interest in:
More than 100 gay men have been detained in concentration camp-style prisons in the Russian region of Chechnya, according to reports by local newspapers and human rights organisations.
The arrests are being made as part of a widespread anti-LGBT purge in the area. The prison camps are the first to be established for LGBT people since the Second World War.
It's difficult to claim the moral high ground when it's obvious your morality is based entirely on your interests. People start to think you're not sincere when you selectively invoke your morality as justification for your actions.
But morality to a government is nothing more than propaganda. It's pulled out and cited when it's convenient to forward one of the government's causes but then buried again once it has served that purpose. When you see a government cite moral grounds for actions know that you're being propagandized. The actions aren't being done for moral reasons, the actions were being done for entirely selfish reasons and morality just happened to be a convenient excuse that sounded far better than greed.
