Role of a right politician

The comments coming from the US President is the way, in which we can understand he is the exact politician.  For the upcoming election, he should have to show his people that, I am a perfect man and wants to keep the peace of the nation and world.  So I have to do something like war and threatening other nations also.   Bush stating that, "enemy declared war on us".  When? Why? He is not ready to go for these two questions.  Whenever he came into the position of President of United States, he started to do war. Just look his words.
"For a while we were marching to war. Now we're marching to peace. ... America is a safer place. Four more years and America will be safer and the world will be more peaceful," Bush said.

Now he is saying that, four more years.  Why? Can he give assurance to his people, America would be safer for ever?  Now, all the Americans has to scare, when they are at their own home and going out.  Because, all the terrorists in the world are taken as a practice court and looking their prior target to America.  If any nation having such kind of leader, then they will never get free-minded sleep.   For his assurance in winning the upcoming election, he should have to wear the peace keeping role.   This is the exact politician, who should change his taste, for "his" bright  and safe future.
