Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe, to assure the survival and the success of liberty.
This much we pledge -- and more. - President John F. Kennedy- January, 1961 Inaugural Address
It's too bad, this message seems to be lost in todays world. Sad.
It is a simpleton approach to interpret that quote as Kennedy saying we will
always go to war in the name of assuring the success of liberty. Don't forget that it was Kennedy that exercised restraint and did not choose military conflict when the Soviet Union parked nuclear warheads 90 miles from the United States in Cuba.
Sometimes bearing "any burden" in support of liberty means not going to war when that would be the easy answer.
And it seems pretty foolish to be suggesting that Bush's war is about liberty, when he is, at the same time making moves to restrict the liberty of our own citizens (i.e., warrantless wiretaps, indefinite detention of citizens without judicial review, etc., etc.).
