Those who committed these cowardly acts may believe that they have shaken our resolve to defeat terrorism. They could not be more wrong.

We remain united with the British, and our allies around the world, in our resolve to defeat terrorism and bring those who commit these acts to justice.

In remembering those who lost their lives in the London attacks and the September 11th attacks we continue our commitment to fighting for freedom, democracy and justice.

137 years later, Memorial Day remains one of America's most cherished patriotic observances. The spirit of this day has not changed - it remains a day to honor those who died defending our freedom and democracy.

I condemn everyone and anyone who commits acts of terrorism. And Hamas has committed acts of terrorism.

Like many Americans my thoughts and prayers are with the people of London. My deepest sympathies are extended to those who lost a loved one in the recent terror attacks.
