Among the signs that we are in the perilous times leading up to the return of Christ is that traitors will be more common. This comes to mind from the news that the recent release of sensitive information on the Afghanistan war by online "whistleblower" WikiLeaks could undermine the U.S. mission there and bring harm to U.S. troops.
One of the factors causing there to be more traitors is the growth of the worldview that we need to be citizens of the world and thus distinctions between nations is holding us back. This motivates world citizens to undermine the United States so that this nation would have less power in the world and need to be more of a team player in the world's community of nations. Indeed this is the same mindset of the ten kings who will yield their sovereignty to the Antichrist... "These are of one mind, and they will give their power and authority to the beast" (Revelation 17:13, NKJ).
Every day there are little reminders like this for the discerning that all things will not "continue as they were from the beginning of creation" (2 Peter 3:4).
