Nuclear Weapons: Today and Tomorrow

Countries such as the United State's and Russia are holding on to their nuclear weapons which is causing political, economic, and military turmoil in the world. While they may be holding on to their WMD's out of fear, or even to assert their powerful position to other countries, they don't need to be. It makes no sense for either country to spend billions of dollars on weapons systems of such radically diminishing strategic utility.
While the nuclear weapons are viewed as a mutual threat by nation's like Russia and the U.S., countries such as Poland and Sweden have something to worry about with the large number of these tactical nuclear weapons. Most of the active sub-strategic weapons in our world today seem to be mostly deployed in Eastern Europe in theoretical preparation for conflict in our part of the world.
Such nuclear weapons are dangerous remnants our world's dangerous past, and they should not be used to endanger our prolific future.
While we are still facing security challenges in the European world of today and tomorrow, but from any angle you look at it, there is no place for the use of nuclear weapons in resolving our current social, political, economic and religious quandaries.
