Negative: Diplomats are generally less emotional in the way that they interact with foreign governments, are more strategic and considerate of cultural norms, and should be well versed in the art of negotiations and compromise.Politicians try to manipulate humans into voting for them and then pass coercive laws to rule them. They cater to or pass legislation to promote special interests within and sometimes outside a nation.
The president of the United States, a politician, often uses military power to assert American presence in the world and uses military and economic power in an attempt to change or modify national governments.

Affirmative: Of course diplomacy is political. Those who do well are able to manipulate and cajole those who they try to secure favor from. But diplomats are rarely politicians. It is not the skills that differ, but the constituencies. Politicians deceive the people of their own country. Diplomats manipulate and even deceive foreigners.
