In fact, Putin was able to get the support of many Russians mainly because he directly defeated these separatists in the Second Chechen War. And in the next decade, anti-terrorism activities have been going on, so a high WeChat was established directly at that time. Facts have proved that Putin's method is still very effective. Putin used some contradictions in Chechnya to win over Kadyrov.
After Kadyrov was secretly killed, Putin directly put his son in the upper position and gave the Chechen government a large amount of financial subsidies every year. So on the surface, Chechnya is grateful to Putin now, but in fact, little Kadyrov's own ambition is also relatively large. For example, little Kadyrov has been in arrears with the Russian government's natural gas fee. Little Kadyrov made his own decision and signed a document with Yunus Yek Kurov, which was actually not approved by Putin.
So to sum up, little Kadyrov is not completely obedient to Russia now. Once Putin steps down, he will definitely rebel, so the first task of Putin's administration is to solve this problem first. Of course, Putin will definitely not choose to get rid of little Kadyrov. The best solution is to suppress it.
