USA did not engineered the Maidan Revolution but welcomed it.
The Maidan revolution was provoked by Putin.
In fact a democratically elected government wanted to pass agreements with west. Putin threatened and the government switched to an agreement with Russia. People revolted.
Zelenski and his government have made mistakes, but they are not fascists, except in Putin propaganda.
I just will give an exemple : European medias can work freely in Ukraine, not in Russia.
When a referendum was held for Ukrainian independence, Russian speaking region voted pro independence.
The only part of µUkraine which was unhappy of belonging to Ukraine was Crimea.
Putin knew that Nato was not ready to integrate Ukraine.
If Putin had wanted negotiate, he would have taken the east of Ukraine, not tried to take whole Ukraine and destroy the country.
Putin is ta dictator, even if not turning as a fascist, installing a dictatorship, killing freedom of press, imposing a set of values, killing opponents, and so.
