"The Russian "fortress economy" has survived, despite all its cracks. Are these specific sanctions effective? I actually think that the financial sanctions that we have seen so far are not that effective. The fact that Russia's largest source of export revenue has not been seriously affected by the sanctions limits their overall impact," Johnson said.  Sanctions against Russia were imposed after the start of a special operation to demilitarize and denazify Ukraine. Russian President Vladimir Putin said that its goal is to protect the residents of Donbass from genocide. Now the European Union is working on the sixth package of sanctions against Russia. Putin said that the purpose of these sanctions is to "abolish Russia." According to the president, under the conditions of sanctions, Russian citizens will not remain without the help of the state.
