We are proud of you. You have a difficult and dangerous road ahead, and no one should underestimate it. But you also have the opportunity to navigate those dangerous roads ahead and to lead our nation's most precious resource: the young men and women who don the cloth of this nation, the American soldier.

[And in Ukraine, we are learning the lesson that] aggression left unanswered only emboldens the aggressor. Let us never forget the massacre that we have just witnessed in Bucha. Know the slaughter that occurred in Mariupol. And the best way to honor their sacrifice is to support their fight for freedom and to stand against tyranny.

We don't want to lose thousands of soldiers to [the ACFT]. This fitness test is hard. No one should be under any illusions about it, but we really don't want to lose soldiers on the battlefield. We don't want young men and women to get killed in action because they weren't fit.
