The Enemy Within

When you think of the term enemy, what comes to mind?

Perhaps you think of a bitter personal or professional relationship. It could be a hard- headed business competitor or maybe you think a foreign fighting force.

In essence, the term suggests that it is someone or something that seeks to do you harm.

That's the working definition of the Internet dictionary:

One who feels hatred toward, intends injury to, or opposes another; a foe.

When it comes to a country, the enemy is most often perceived as another nation, usually with an opposing political ideology.

At least that's what it used to be.
