Russia is also an enemy of the West, but why did Islamic State attack? :1,400 years of history

Russian President Vladimir Putin often threatens Western countries including America. They believe that western countries including America, European Union are against them and are supporting Ukraine in the war. This is the situation of Russia since the Cold War. Similarly, all Islamic terrorists including the terrorist organization Islamic State also consider Western countries as their open opponents and enemies. Why the Islamic State launched a massive terrorist attack on Russia is a question, given that Russia itself has been an enemy of the West. 140 people have tragically died in a terrorist attack on a concert hall in Moscow's Crocus City.

Experts who understand the ideology of the terrorist organization Islamic State believe that Russia is like their enemy. The reason for this is that the number of people following Christianity is high in Russia. Islamic State has divided much of the world from Pakistan to Nigeria in a centuries-long war. He believes that there has been a war going on between Islam and Christianity for the last 1400 years. In this, all Christian majority countries are on one front and Islamic countries are on another front. He believes that Moscow is also part of a broader organization of Christians.
