The EU remains our dream. We must not give it up. Otherwise Putin would win. His goal is to undermine the EU. This is not only about a conflict between Russia and Ukraine. Russia is fighting against the West and its values. Therefore, the European project of Ukraine must not fail. We know that this aim requires successful reforms in Ukraine, even if they hurt now.

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.

Merkel is a flagship of the EU. Not everything depends on her, but much does. I have been shocked in a positive way by how Merkel is defending international law so openly and strongly. She wants to have peace and stability in the EU, and she knows that Russia is a problem in terms of security. It seems to me that many Germans are led by a certain fear of Russia. So you hear things like, "Let's avoid conflicts with Moscow, let's appease the Kremlin."

If 85 percent of Russians support the annexation of Crimea and the aggression against Ukraine, that is a very bad sign. The post-Soviet legacy is a heavy burden: Most Russians want to have the empire back. The only way it is possible to make that happen is to seize foreign territories.

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.

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.
