This article only wants to give a general understanding to some melon-eating masses, or people who do not understand it very well.

NATO's confrontation with Russia in Ukraine
First, let's take a look at the geographical location of Russia and Ukraine
Ukraine is located in the east of Europe, bordering Russia to the east, the Black Sea to the south, Belarus to the north, and Poland, Slovakia, Hungary, Romania and Moldova to the west. Ukraine is geographically important and is the geopolitical intersection between the European Union and the CIS, particularly with Russia.
Russia, located in the northern part of Eurasia, spans two continents of Europe and Asia, with a land area of 17.0754 million square kilometers, is the largest country in the world. From the map, the latitude span of Russia is relatively large, spanning 30 latitudes from north to south, and the longitude of the east-west direction spans 150 degrees. In the south, Russia is adjacent to China, Mongolia, Kazakhstan and other countries, and to the west is adjacent to Finland, Ukraine and other countries.
Russia is not rejecting Ukraine, but Ukraine has always wanted to join an organization, which is NATO.
The North Atlantic Treaty Organization, or NATO for short, is an international military bloc established by North American and European countries to achieve defense cooperation.
As you can see from the map, in addition to Ukraine, Belarus, basically Russia has been surrounded by NATO. Belarus is a staunch ally of Russia, so the only thing that has changed is Ukraine!
Ukraine inherited a lot of military equipment from the collapse of the Soviet Union, and countless factories, from strategic bomber White Swans to nuclear weapons and nuclear facilities. Although Ukraine's heavy industry is well developed, light industry is pitifully small.
The "White Swan" strategic bomber, the country's heavyweight
Abandoned military equipment
When the Soviet Union collapsed, there were many "high-ranking officials" in Ukraine who took advantage of the imperfect constitution at the time of the dissolution to rapidly expand their industries, and finally became a well-known "oligarch" in Ukraine, these people controlled most of Ukraine's resources, from banks, real estate, steel, coal, chemicals, etc. There were "oligarchs" involved, and ordinary people could only get very few resources.
Ukrainian oligarchs, who basically "controlled" Ukraine
There are basically only two kinds of people in Ukraine, one is the "oligarch" and the other is the poor, so Ukraine has been in an economic downturn, and there is no substantial construction and development.
Private armed forces of Ukrainian oligarchs
Although Ukraine has always wanted to join NATO, NATO does not want to accept this "street slipper", but only wants Ukraine to become a pawn to contain Russia.
Russia and NATO are not suddenly in serious conflict, but accumulated over time, to give you a simple combing.
In 2007, relations between Russia and NATO began to cool. Putin's speech at the Munich Security Conference became one of the symbols. Sergei Ryabkov (then director of the Department of Pan-European Cooperation at the Russian Foreign Ministry) declared that Russia's link with NATO was only to combat drug trafficking.
In 2008, relations between Russia and NATO were revived by discussions within NATO about the possibility of Ukraine and Georgia joining the NATO action plan. Russia sees this as a sign of NATO's intention to expand east, calling it a threat to Russia.
In August 2008, the rift between Russia and NATO deepened as a result of the Five-Day War in Georgia. Since then, the implementation of the Russian-NATO Council meeting and a series of joint projects has been suspended until the spring of 2009.
In March-April 2014, after the outbreak of armed conflict in eastern Ukraine, relations between Russia and NATO deteriorated completely, and almost all cooperation was suspended. On April 8, NATO banned almost all Russian staff from entering the NATO headquarters building, with the exception of ambassadors and others, and ordered that the number of permanent representative offices be reduced from 70 to 50.

NATO has expanded eastward step by step, a total of 5 times, from 1999 to the present, NATO has advanced more than 1,000 kilometers to the east, which is also the source of the outbreak of the Ukrainian crisis.
NATO has exerted pressure on Russia one by one, and Ukraine has no eyesight to see it, and it wants to join NATO.
Nato has two kinds of forces, one is pro-European and the other is pro-Russian. The current Ukrainian president, Zelenskiy, is pro-European, so relations between Ukraine and Russia are becoming increasingly tense.
Ukrainian leader Zelenskiy
Most people in the world feel that Putin does not dare to fight, but Russia has really moved!
Russia directly declared the independence of the two pro-Russian oblasts and directly attacked Ukraine.
In an hour or so, Russia has largely eliminated Ukraine's air and naval threats.
In a day or so, we arrived near Kiev, the capital of Ukraine
Russian leader Vladimir Putin
Ukraine has always been a "front line" against Russia, and if Ukraine joins NATO, Russia's homeland security will be seriously threatened.
Missiles deployed inside Ukraine can reach Moscow in 5 minutes, which is equivalent to having put a gun on the door of the head. If we continue to choose to tolerate it now, NATO and the United States will become more aggressive, and Russia will become very passive.
There are many people who are "sympathetic" and think that the Ukrainian beating belongs to the party that needs support, but those who have roughly understood Ukraine will feel that the Ukrainian "beating" is really self-inflicted. A vigorous provocation of Russia, Russia and you reason, you play a rogue. Russia is doing something to you, and you want to be reasonable?
There is no "neighborly relationship" between countries, only politics, security, and interests.
If I don't hit you, I'm going to get beaten!"
The great leader once said: Throw one punch, so that a hundred punches will not come!!!
