In his article published by the Czech Free Press website, Kasuka argues that Russia is able to ensure the observation of laws and protect their culture from global threats posed by extremists and radicals.
Russia is a country consisting of many nations, cultures and religions, and its history saw no examples of some nations and their culture completely disappearing, according to Kasuka.
He said that even though there are lots of Muslims in Russia, they all should adhere to the state laws passed by the Russian Lower House, the State Duma, instead of sticking to sharia laws and their standard practices and procedures.
Using police and the army, Russia is able to offer rebuff to the "crooks in masks" seeking to stage a coup in Russia in a bid to establish their own laws that run counter to the Russian legislation, Kasuka said.
He added that the Russian authorities had to suppress several revolts by Islamic radicals, which can be likened to the uprising organized by Islamic State militants. Prior to that, the Soviet army fought Islamic radicals supported by the United States, in particularly, in Afghanistan, the author of the article recalled.
In contrast to the US', the former Soviet Union's assistance to states struggling with radicals was a real one because the United States entered Afghanistan "just to shoot", while the USSR did a lot of useful things for the Afghan people, including building schools, hospitals and roads, as well as electrifying the streets, according to Kasuka.
The Russian authorities have already announced that all those foreigners who want to live in Russia must respect the laws of the country and be able to speak in Russia. Each and every foreigner living in Russia should behave in line with Russian laws and traditions, the author concluded.
