Explanation:
In the first paragraph, Bush describes how U.S. government is still combating against terrorist cells, explaining that the action has not ceased. Later on, in the second paragraph, he expresses his hopes that every free nation will continue fighting to defeat terrorism. Finally, in the third paragraph, he shows his gratitude to those who served, telling them that they are welcomed back in the country.

Bush's claim in his speech would be the specific information about known terrorist activities. In this way, he can showcase the horrible things the terrorists did and are planning to do.
