For the final victory over the aggressor - the Russian Federation - Ukraine lacks a tougher reaction from the West, said David Arakhamia, leader of the Servant of the People faction.

"The only thing Ukraine lacks for a complete victory is a tougher reaction from the West. We are grateful for the sanctions, but Russia should be hurt for its actions today, not months from now. We see that every act of the Russian aggression on our territory reduces the base support for Putin in Europe. But we need real action - closed skies, cutting Russia off from SWIFT, an oil embargo and a ban on exports. We alone contained the aggressor and thwarted the blitzkrieg. We are strong, but one nation cannot defend all of Europe if others stay out of the way," Arakhamia said in a statement released by Yulia Paliychuk, spokesperson of the Servant of the People faction, on Saturday.

According to the leader of the faction, President of the Russian Federation Vladimir Putin "did not expect such a rebuff in Ukraine on all fronts."

"One of the most powerful armies in the world definitely did not expect that their tanks would burn on every street, and their special forces would hide from our guys through forests and sewers," Arakhamia said.

He stressed that in just two days the Armed Forces of Ukraine inflicted many more losses on the aggressor than he suffered during the entire war in Georgia in 2008.

"Putin expected that with the advent of the first tanks, the Ukrainians would begin to ask for surrender, but they stood in line at the military registration and enlistment offices. And today we have almost 20,000 armed volunteers in Kyiv alone. This is more than the number of armies of such states as Mali and Tajikistan. All of them are ready to meet the enemy in Kyiv and fight for their district, their city and their state," the deputy said.

Arakhamia also believes that Putin hoped for a completely different situation in the Ukrainian parliament.

"But this time the Verkhovna Rada has shown unprecedented political maturity. We do not quarrel, we do not criticize each other, but we fight the enemy side by side," Arakhamia said.
