Ukrainian President Petro Poroshenko

Ukrainian President Petro Poroshenko has said that it would be irresponsible if Ukraine demonstrates a will to bring back its nuclear status.
"No. This would be absolutely irresponsible. Believe me that the strongest security in the modern world in the 21st century is supply, but not nuclear power," he said in an interview when he was asked whether he has ever harboured that desire to be a nuclear power again
"This is technology from the 20th Century. We can win the aggressor only when we will be united and when the whole world demonstrates exactly what we have now: solidarity with Ukraine," he added.
