When we were attacked militarily it was our duty to defend our country.

Putin's survival depends on land grabs of foreign territories. He needs new annexations. The annexation of Crimea has gained him much applause at home. But that will not last forever. The Western sanctions are beginning to take hold and the people are suffering. In order to maintain his popularity, Putin has to commit further international crimes. Otherwise he will be dead politically.

I'm always very cautious about "brotherhood" concept. Frankly speaking, I don't need such relatives who grab my land and kill my people.

It is positive that the United States and the European Union show a great deal of unity. Putin did not expect that. He thought he could split the EU, but the opposite happened: The EU imposed sanctions and even scaled them up. Of course we need more financial and military aid, the supply of lethal weapons is of crucial importance to us.

The Russians will always find a pretext for their aggression. It was Putin who said in 2005 that the biggest geopolitical disaster of the last century was the collapse of the Soviet Union. Putin wants to bring Ukraine back into the Russian sphere of influence. That is why he tried everything in order to stop the EU-Ukraine Association Agreement.

We are not only facing economic disaster and the question of peace and war. Ukrainians are traumatized by this Moscow-led aggression that has cost the lives of 5,000 people.

We stand firmly behind the decision made at the summit in Bucharest where it was decided that Ukraine could one day become a member of NATO. That is not only in the interest of Ukraine, but also in the interest of Europe and peace on our continent. But we also know it will take a long time until Ukraine fulfills the standards for NATO membership.
