German Foreign Minister Johann Wadephul has said Russia must face increased pressure after recent airspace violations in Poland and incidents in Romania. "Russia must know: we will always respond," Wadephul told German public broadcaster ZDF on Sunday. "We will not allow ourselves to be put under further military pressure. We will unleash our powers, and the economic and political powers of the free world are strong." Wadephul said Russian President Vladimir Putin was "testing" the West. "He does not accept any offer of talk. He clearly does not want to end this war in Ukraine for now. He is going beyond it, and we must respond clearly and stand united," the German foreign minister said. Wadephul said he is in favor of tougher sanctions against Russia but stressed that NATO's defenses at its eastern border had to be strengthened.
