All those persecuated one man's terrorist is another man's freedom fighters etc, political asylum west provides foreign dissidents (or what foreign actors consider dissidents) out of human rights. Frequently they settle in west and move on with their lives. The issue arises when these people organize and create movements or organizations to influence foreign policy of new host country to go against interest of where they fled, or independantly meddle to undermine. Many so far assumed western influence, more or less depending on functional immunity from extradition allows them to operate unmolested. IMO more countries with reach realizing it's fine to meddle in western sovereignty as long as west allows their citizens/diasphora to meddle in theirs under excuse of liberalism/free speech/association etc. And obviously people in "free" societies with right to influence foreign policy, may still, but govs ability to protect them from motivated actors will likely decline.
