He stated this in an interview with Censor.NET.
"I personally did not vote. Someone voted with my card. The decision of the Communist Party faction was to vote for the accession of Crimea, and they used my card, although I did not authorize anyone to do that. Then I saw what serious consequences this vote had led to, and I still believe it was a gross mistake. My personal mistake, and Russia's mistake. And this mistake should be corrected," Voronenkov said.
The effects of Crimea's annexation will be very difficult for Russia itself, the ex-deputy believes. Since in addition to the inability to develop in conditions of international sanctions, the Russian authorities still have to invest heavily in Crimea at the expense of other Russian regions.
"Having annexed Crimea, Russia began to invest a lot of money there. These funds are used to the detriment of other native Russian regions. Russia's most impoverished regions are indigenous Russian regions such as Ivanovo, Ryazan, Vladimir, Vologda, Pskov Oblasts. The imbalance in supply for the regions is huge. Caucasus, for example, receives billions of dollars in subsidies. Entire Russia has been stripped of financing in favor of Crimea. The consequences for the country are heavy, they hamper any development. Having committed an act of aggression against Ukraine, Russia quarreled with the world community. This was done even in violation of the Russian federal law on referendum. Now that Russia is under sanctions, anti-Russian sentiments in the world are swelling, investments have been cut and access to Western credit resources has been denied...
"As one well-known writer put it: 'What unites Russian Ivan and Magomed? An opportunity to snatch something.' Then all national, religious and linguistic differences disappear. Crimea was a litmus test, it united Russia around the idea of swiping something from its neighbor. And many citizens of Crimea would have acted similarly - they have the same way of thinking. If Americans came to Crimea and said it would be America, and pensions would amount to $1,000, they would vote for America," Voronenkov said.
