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

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.

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.

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."

My aim is not to start a new offensive against Russian soldiers, but to deter Russia from further aggression. The thing is that the EU is always playing by the rules. Putin is always playing with the rules. At the beginning, many thought that, after annexing Crimea, the beast would calm down. But he continued by supporting the so-called separatists in eastern Ukraine.

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.
