German Chancellor Angela Merkel's government voiced immediate concern over US President Donald Trump's threats to pull out of the INF nuclear arms treaty with Russia. Berlin said it "regrets" Washington's decision, adding that it urged Russia to "dispel the serious doubts about its adherence to the treaty that had arisen as a result of a new type of Russian missile."

German Foreign Minister Heiko Maas said that Trump's move poses "difficult questions for us and for Europe" since the INF treaty is "an important pillar of our European security architecture."

Maintaining the level of security in Europe was the primary concern of German Defense Minister Ursula von der Leyen. "Regardless of whether the treaty has to be saved or renegotiated, it is important that all NATO states be included in the discussion," she told reporters during a trip to China.

The International Campaign to Abolish Nuclear Weapons (ICAN), which won a Nobel Peace Prize last year, called on Berlin to intervene in the tug-of-war between the US and Russia. The potential threat to people living in Europe is massive, warned Johannes Mikeska, the head of ICAN's Germany branch. "That's why it is urgent for the German government to now mediate between the US and Russia," he said.

The Greens described Trump's move as "absolutely fatal." Annalena Baerbock, the co-leader of the Greens, urged Merkel's government to take a stand against Washington by getting rid of the US nuclear weapons still stationed in Germany. "If the German government is serious about its appeals to the US government, it must now say: 'We are ending Germany's nuclear participation,'" she said.

Christian Lindner, the leader of the business-friendly Free Democrats (FDP), said although he thinks Trump's decision is "dangerous," Washington's reasoning was sound. "What's correct is that Putin isn't adhering to the INF!" Lindner wrote on Twitter. The FDP chief also slammed the Greens' proposal to remove US weapons from Germany, saying it would leave Germany "defenseless."

The deputy leader of the FDP, Alexander Graf Lambsdorff, told DW that he was deeply concerned about the type of cruise missiles that were prohibited by the treaty. He noted that it "concerns a category of weapons that would reach Europe — not the continental United States." He added that he believes the treaty can be saved "if all sides share the intention of avoiding a really ruinous arms race."
