In my opinion your mindset is wrong on this issue. You want to address the effect and not look at the cause. It’s like living in the forest but we can’t see any trees.
Unless the West, and more importantly, the Muslim world, wants to address hardline Islam then problems like what we are witnessing in Myanmar and many other places around the world are never going to go away. Hardline Islam is terrible for everyone, the west, the east, the middle east, the innocent and the non-believers. More importantly, hardline Islam is a terrible outcome for Islam and Muslims.
When ISIS advertised they were wanting to build a caliphate in the Middle East they didn’t get a few hundred unstable, blood-thirsty individuals wanting to join the group, they got hundreds of thousands of Muslim sons and daughters from all around the world wanting to join. The numbers were so great that many governments were forced to introduce new laws to stop their Muslim citizens from leaving to join the caliphate builders. I spend a lot of time in Indonesia and it is clear to see the effects hardline Islam is having (influenced by Saudi money and radical Saudi clerics) on this beautiful country and its wonderful people.
Yes, the western world can spend 100s of billions of dollars on security, cameras and bollards but if nothing is done to address hardline Islam, then the on-going cycle of violence will continue. Most of the world accepts that the majority of Muslims are loving and peaceful people but there are hardline elements which are, and will continue, to cause problems for Muslim communities, Muslim countries, and the rest of the world. Until the killing of innocent people in the name of Islam is stopped then it will always be difficult to argue that Islam is a loving and peaceful religion. And this will require a hard and difficult look within Islam to eliminate what causes so many of its sons and daughters to commit appalling acts in the name of God. One that the Islamic world has been unwilling to undertake at this point in its world history.
If America doesn’t want to address gun control then the mass killings will keep occurring in their country every week. If the Muslim world doesn’t want to address the hardline elements living within their communities and/or countries, then the Islamic related killings will continue around the world every week.
I think it is unfair to point the finger at China, India, Russia, and Myanmar while the Muslim world is unwilling to address hardline Islam.
