The rise of "Islam", or should I say Salafi (inspired) ideology/pan-Arab Islamism, is proving to be a huge challenge internationally. Nigeria, a country I have lived in for 4 years, is now becoming a hot-bed for the Boko Haram "Islamists", inspired by pan-Arab Islamism, with links to the AQIM (Al-Qaeda of the Maghrib). I have visited Kano in Northern Nigeria myself, I know people from there, & there is definite foreign funding for the Madrassahs there that breed extremism.
Not only is this ideology a disgrace to Islam & Muslims, but also facilitates foreign powers with great geopolitical ambitions to advance their objectives in the region. Pan-Arab (inspired) Islamism is on the rise not only in the Middle East, but also in Central Asia (Uzbekistan, Tajikistan, Kyrgyzstan, Kazakhstan, Azerbaijan, Chechnya etc), as well as other parts of the world; even affecting nations in the Asia Pacific (China, Myanmar, Indonesia, Philippines etc). Nations, that were once relatively secular, are seeing the rise of these "Islamists", who threaten to disturb the "balance of societies" all over the world. Some people think of this as an Islamic revival, although all the societies these "Islamists" administer are the most backward, uneducated, impoverished, intolerant ones.
There is also a rise of a troubling ideology in the Muslim world, with its followers wishing to install 'the caliphate' over their respective countries. There is no clear definition on what this caliphate will be, although it is inspired by pan-Islamism as well. This ideology is threatening to radicalize people that were not radicalized previously. The Muslim world needs to reform itself if it wants a real revival.
At the end of the day, while some people might view these things as the "revival of Islam", it is abundantly clear that these "Islamists" are a bane to Muslims & Islam all around the world, & are in bed with powers with huge geopolitical ambitions.
