John Kerry: 'The world has lost a transformative leader'

I was saddened to learn of Baroness Thatcher's passing, and Teresa and I join millions across the United Kingdom and around the world in mourning her loss and celebrating her life. We pray especially for Carol and Mark and their families.

The United States has lost a dear friend, and the world has lost a transformative leader who broke the glass ceiling in global politics. With her characteristic determination, she defined grit on the world stage and grace in the face of advancing age and illness.

Lady Thatcher took the helm of government amid tumultuous times. She would face wars abroad, terrorism at home, and deep uncertainty about the United Kingdom's future. She met all these challenges and many others with unyielding drive and courage.

We celebrate especially the way, with a hand outstretched across the Atlantic, Lady Thatcher strengthened the Special Relationship between the United States and the United Kingdom-a relationship that remains a driving force for freedom, justice, and democracy.

In 1985, when I was a newly sworn Senator, Prime Minister Thatcher spoke to our Congress. The threat of a Soviet Empire she warned against has given way to a new set of global challenges, but our alliance with the United Kingdom remains an unrivaled source of strength in today's challenges from Afghanistan to Syria.
