With the last message (this link contains full speech) to the Federal Assembly, president Putin proposed some constitutional changes, main point of which - in reorganization "vertical of power" in Russia. Along with that, Putin announces changes in inner politics, especially in demographic politics.
Main point of constitutional changes - shifting government appointment from president to parliament, and so weightening role of parliament. In generally, Russia stays a strong president republic, as China, for example. Some general information about Russian structure of power can be picked from wikipedia.
What does it mean inside Russian structure of power? More responsibility for parliament. President still can fire every government member, but since now, government is appointed not by president.
As long as this is enough "shock" changes, PM D.Medvedev resigns. And then president Putin immediately appoints new PM - Mikhail Mishustin - after few hours of D.Medvedev resigns.
The main point of PM and government resigning - the sudden start of structure reforms in Russian power structure.
Main points of the message to Federal Assembly:
- Fighting poverty - donations for poor families with children younger than 7
- "Mother's capital" now payed not for second and above children, but now for the first child born in family too. Russian "Mother's capital" is one-time donation to the family for the child born. In 2019 it was 453,026 rubles (about 7300 US dollars). Along with it, there are some month donations, but they are lower and vary in different regions.
- Investments stimulation for real economics with lowering tax on income for companies.
What does it mean to other countries? In fact, nothing. This message to Federal Assembly was nearly fully about inner politics. Of course there are some words about US, as main political opponent, but not very much.
What is next in terms of political procedures? All along to wikipedia - President appoints new ministers. New PM was appointed few hours after previous PM resigns.
For readers, opposite to Russian political system - I respect your point of view, but I doubt if such constitutional changes directly mean "grabbing power by a dictator". You surely may make proposals, and then make considerations over your proposals. But it looks like more a conspiracy than interpretation of an event.
