If America ends up at war, it almost certainly will be on behalf of one ally or another. Washington collects allies like most people collect Facebook "friends." The vast majority of U.S. allies are security liabilities, tripwires for conflict and war. Alliances should be based on interest, not charity.
Just as Facebook strengthens connections between peers, it can also enhance bonds between family members by allowing them to stay updated on each other's lives and maintain contact easily. However, there are many Facebook functions, that if used inappropriately, can drag you across a boundary from which your child or grandchild would have preferred to remain uncrossed.
