Which political belief is shared by countries that practice genocide? perpetrators of ghastly crimes should remain free. peacekeeping missions threaten governmental control. the government must be respected. those who are different are enemies.

The correct answer should be Those who are different are enemies.

Genocide is based around the idea of exterminating an ethnic ethnic population based on their difference from the people committing the genocide. It's not about respecting government or about government control but rather around the idea that they don't have the right to be there or to live or anything similar and should be executed for being different.
