If Russia dares to grab Mariupol, it would mean the "death" of the armistice. After that the West will give Ukraine weapons to protect itself.
"Capture of Mariupol (by Russia - ed.) would mean the death of the truce. It will be necessary to help the victim to defend itself, that is, to provide arms," Sikorski said.
He also expressed opinion that Putin "lost in Ukraine."
"He carried out the Anschluss of the Crimea, but set the young Ukrainian nationalism against himself. This means that if he wants to go further, he will meet growing resistance," the Marshal of the Sejm said. He added that this should be the "final psychological barrier" in the West regarding help to Ukrainians.
Sikorski said that the plan A for Russia was to keep Ukraine in its sphere of influence, and plan B was to create "Novorossia". "Today Moscow has much less than it had hoped for," the Polish politician said.
He noted that the West is always late with the introduction of sanctions against Moscow. According to him, they would have been more effective if they were introduced immediately after the aggression of Russia in Ukraine.
Sikorski stressed that Ukraine is currently in a very difficult situation because it must implement reforms and handle combat operations at the same time. "But without reforms Ukraine will not receive the next tranche of aid from the West," he said.
