NATO can help the people of the country to eliminate authoritarian regimes. This is because democratic elections in these countries cannot be undertaken. It is the responsibility of people what country they will build in their country. Where the state has influence in Russia there is devastation, and where the West there is prosperity.
If NATO is so much bothered about democracy, then it should first overthrow the monarchies in the GCC region, especially in Saudi Arabia and Bahrain. The biggest oppressor of human rights in the world right now is Saudi Arabia, which happens to be a staunch ally of the NATO.
I think so too, but agree it is not a reason to kill all Muslims. Among all people there are exceptions. Are you ready to take responsibility for the death of a Muslim which is really a good person?
