"He shall judge between the nations,
and impose terms on many peoples,
They shall beat their swords into plowshares
and their spears into pruning hooks;
One Nation shall not raise the sword against another,
nor shall they train for war again."
(Is 2:4)

Above is the Messianic Ideal of Peace among nations which is not automatic but can only be worked toward by men of good will. Toward the end of the Second World War came the realization that unity promotes order, harmony and peace while disunity causes disharmony, revolt and war. Thus the United Nations was created in 1945 to harmonize the workings of nations. The purposes of the United Nations are as follows:

1) To maintain peace and security in the world.
2) To develop friendly relations among nations.
3) To achieve international cooperation in solving economic, social and cultural problems.
4) To promote human rights and freedoms.

The biggest problem the UN faces is the prevention of proliferation of nuclear weapons and its ultimate elimination.

In 1963 Pope John XXIII wrote the following: "Men nowadays are becoming more and more convinced that any disputes which may arise between nations must be resolved by negotiation and agreement, and not by recourse to arms. We acknowledge that this conviction owes its origin chiefly to the terrifying destructive force of modern weapons. It arises from fear of the ghastly and catastrophic consequences of their use." (Encyclical Pacem in Terris of John XXIII, 11 April 1963, #126-127)

We are now in 2010, forty seven years later and the world has a total of about 24,000 nuclear heads one of which alone could wipe out the entire city of New York. Barak Obama in his 2009 speech in Prague has spelled out the predicament thus, "The threat of global nuclear war has gone down, but the risk of a nuclear attack has gone up. More nations have acquired these weapons. Testing has continued. Black market trade in nuclear secrets and nuclear materials abound. The technology to build a bomb has spread. Terrorists are determined to buy, build or steal one. Our efforts to contain these dangers are centered on a global nonproliferation regime, but as more people and nations break the rules, we could reach the point where the center cannot hold." (Barak Obama Speech in Prague, April 5, 2009)

Barak Obama has pledged the United States would seek the peace and security of a world without nuclear weapons. This means stopping production of weapon grade materials, reductions of nuclear weapons, banning testing of nuclear weapons, establishing an International Fuel Bank for the peaceful use of fission material, enforcing the Nonproliferation Treaty and as long as nuclear weapons exist to build and maintain a defense system.

"Blessed are the peacemakers, for they shall be called children of God." (Mt. 5:9)

Prayer of St. Francis

"Lord, make me an instrument of your peace,
Where there is hatred, let me sow love;
where there is injury, pardon;
where there is doubt, faith;
where there is despair, hope;
where there is darkness, light;
where there is sadness, joy; ..."
