Undersecretary of War for Policy Elbridge Colby called for the United Kingdom to increase its military strength a day after British Defense Secretary John Healey resigned from Prime Minister Keir Starmer’s government.

Colby weighed in on his resignation on Friday morning, saying on social media, “The United Kingdom has an extraordinarily proud military history. It commands our respect. There is again a great need for more British military strength in this critical time. We urge the UK to meet that need with urgency, scale, and determination.”
