In the U.K,all the social problems already noted plus the harvest of alcohol binge culture and drug culture.

The rise of China as a world power could be a plus or a negative.

And last but not least,the continuing support to failing countries which is more and more a drain on limited resources,a hard but true fact.What is the greatest threat of the 21st Century? Choices inside, or choose your own...?The biggest threat to our security is that we are falling from within because of the economic instability. The only way to solve the problem is to have tens of millions more sustainable jobs and give the lower middle class massive stimulus. Nothing else will solve our economic woes. Our backbone is deteriorating and we must prop it up for our future.What is the greatest threat of the 21st Century? Choices inside, or choose your own...?
Obama... plain and simple. He is destroying the world's greatest society, economy, and residence for freedom. Mandatory healthcare? Taxing foods he doesn't feel we should be consuming to get us to change to his way of thinking? Gas prices almost doubling to force us into decisions we otherwise wouldn't make. Other countries laughing at us because of his constant apologizing and bowing to other leaders. Nominating a supreme court justice who has no business being there. Jumping to conclusions in situations that affect his friends and turning it into a media circus. Increasing racial and religeous tensions throughout the country. Losing some of our strongest allies and making this world a much less safer place for us to be Americans.What is the greatest threat of the 21st Century? Choices inside, or choose your own...?Religions are the biggest threats. They are oppressive and narrow minded. They often persecute others of different nationalities and religions. They promote violence and racism. Stop the oppressions and ban all religions.
Oil/Natural gas shortages because they cause all the other problems, since the economy runs on fossil fuels, and politics are based on economics, and politics cause terrorism.What is the greatest threat of the 21st Century? Choices inside, or choose your own...?
Terrorism, stupidity, selfishness, hatred towards others, political rowdyism, lack of self-control, aggression.
