 Who is behind the Russia attack?

A terrorist attack targeted Russia today

Crocus City Hall terrorist attack 

Hours after the attack, as expected, ISIS announced it She was behind the attack in Moscow

What is clearly visible is that the ISIS scarecrow story is nothing more than a mask behind which the actual masterminds of the attack hide

If this organization does not carry out operations in Palestine and Gaza, it will be subjected to genocide by the nearest Palestine or Russia. 

It is said that this is just a plan from Putin himself, who was behind the attack, in order to use it as a shield for the larger invasion of Ukraine, as stated by French President Macron.

The United States and Britain warning their citizens hours before the  attack occurred puts both countries in the dock. How could they have known about the attack before its time, belittled their citizens in Moscow, and not informed the Russian authorities? 

US intelligence may have informed its Russian counterpart of the possibility of an attack, but they did not take it seriously 

The attack in central Moscow gives an indication of some weakness in the work of Russian security forces 

Most countries, including the United States of America, condemned the terrorist attack that affected Moscow, but Putin accused the United States of America of being behind the attack and using ISIS as a cover for its actions. 

Investigations are underway, and according to Putin, whoever was behind the attack will pay a heavy price. Remember that after the attack, there was a drone attack on an oil refinery station in Russia. 

The United States of America, ISIS, or Putin, who is the most prominent accused?
