I understand what you are saying in that perspective, and in that context you are absolutely right. President Bush acknowledged it was his fault, and we both can agree that it did happen on his watch.
But after 9/11, President Bush certainly did take action and he *did* keep us safe; more so than, I believe, President Clinton or President Carter would have. At least he went to work early, attended intelligence briefings and unlike those in the current administration he didn’t spend an inordinate amount of time on the golf course and vacations. Syria disclosed its biological weapons program as a result of President Bush, for example.
I do not intend to vote for Governor Jeb Bush for the office of President. However, saying that he lied is probably a little unfair.
See the truth is neither fair or unfair it is one thing only the truth.
Bush was POTUS, the man in charge the big cheese etc. On hisis watch nearly 3000 Americans died on American soil at the hands of foreign enemies of the state. So saying he kept America safe on his watch is not truth. And when you are not telling truth then you are lying, whether by ignorance or deliberate action it still does not change that fact that the statement is a lie.
