Austin announces increase to US military presence in Germany - CNN

And so we will continue to strengthen our partnership and our alliance," he said.

Germany's Minister of Defense Annegret Kramp-Karrenbauer welcomed the announcement of an additional 500 US troops stationed in Germany as "happy news" and said the US' commitment to NATO is "a crucial pillar for our freedom and peace."

"Our cooperation is all the more important, important in times where the security and defense architecture has come under pressure in many parts of the world," she said appearing alongside Austin Tuesday.

Austin will continue on his first trip to Europe as defense secretary this week, joining US Secretary of State Tony Blinken in Brussels to meet with NATO allies.

Blinken on Tuesday reiterated that "the United States stands firmly behind the sovereignty and territorial integrity of Ukraine" during a meeting with Ukrainian Foreign Minister Dmytro Kuleba in Brussels.

The top US diplomat said that support was particularly important in light of Russia taking "very provocative actions when it comes to Ukraine."

"We're now seeing the largest concentration of Russian forces on Ukraine's border since 2014 and that is of deep concern not only to Ukraine but to the United States and indeed to many of our allies and partners," Blinken said, adding that he'd be consulting with NATO partners in the days ahead.

Kuleba expressed appreciation for the US' support and expressed optimism that the international community would take "actions that will make it very clear for Russia that the price of its further aggression against Ukraine will be too heavy for it to bear."

US European Commander Gen.

Tod Wolters told Congress that Russia has an "inject of a very sizable ground domain force" near the Ukraine border, as well as a "notable air force injection and a notable maritime force injection."

"It is of the size and scale and scope that is of great concern," he said Tuesday during a Senate hearing, adding that the Russian force today mirrors that of its 2014 infiltration.

Austin plans to meet with NATO Secretary General Jens Stoltenberg on "how the Alliance is tackling destabilizing behavior by Russia, a rising China, terrorism, and global challenges such as COVID-19 and climate change," according to the Pentagon.

The Trump administration announced last year it would withdraw nearly 12,000 troops from Germany in a plan that would have cost billions and taken years in order to relocate the troops.

The decision was met with broad bipartisan push back amid concerns that it will weaken the US military's position in regard to Russia.

In February, President Joe Biden said he was halting the troop drawdown, framing his decision as critical to strengthening Europe's defenses.
