Ukrainian parliamentarian, leader of the European Solidarity party Petro Poroshenko, when speaking at the session of the NATO Parliamentary Assembly in Canada, called on the members of the Alliance to give Ukraine an invitation. He stressed that this would be the right response to Putin's escalation, the European Solidarity said on its website.

"When we now see the message that Putin sent to the world by attacking us with an intercontinental ballistic missile, sending 12-15 ballistic missiles per night to Kyiv, to critical energy infrastructure facilities - whom is this message addressed? To Ukraine. We are not afraid. This is the message to a ‘weak’ Western nation," Poroshenko stressed.

"What is the main component of our victory? Membership in NATO. We can win this war without firing a single shot, with just one signature. And this is the signature of Ukraine's invitation to NATO. This will change everything at once. Demonstrate that Putin cannot blackmail not only Ukraine, but also the free democratic world. We need this signature now," Poroshenko stressed.

He called for allocating at least 0.25% of Western GDP to support Ukraine.

"I want to draw your attention to the figures released by the Ukrainian intelligence service. North Korea and Iran supply Russia with more artillery shells than all NATO countries do to us. They supply more missiles than all NATO countries. This means that they are putting their economy on a military track, and we think that ‘somehow it will be,’" Poroshenko said.

"No one in the world understands why we should not get permission to sign an invitation for Ukraine. Why tie Ukraine's hands if over the past two weeks we have been demonstrating the unique effectiveness of the Armed Forces of Ukraine. With not only Russian, but also North Korean positions destroyed," Poroshenko stated.

"So, now signing the invitation to NATO is the right answer to Putin. And I want to remind you that this is the cheapest option. This is an option to avoid a nuclear catastrophe," Poroshenko said.

He recalled the "red lines" regarding Ukraine - there can be no compromise on Ukrainian sovereignty and independence and no compromise on the territorial integrity of Ukraine and no compromise on the Ukrainian Armed Forces.
