1. The United States of America:
US Army is the No. 1 Strongest army in the world by strength, technology and weapons and active personnel. The United States Armed Forces consist of the Army, Marine Corps, Navy, Air Force and Coast Guard. The President of the United States heads the military. The country has been a major power in defence and has engaged itself in numerous operations and missions in the world including freedom operations and missions against terrorist groups in various parts of the world. The active personnel in the United States Armed Forces is about 1,301,300 with about 811,000 reserve personnel, that is one of the largest in the world. It is the pioneer in having nuclear weapons and now is a prime power in many peacekeeping alliances and to provide humanitarian aids in case of emergencies.
This huge military strength of these countries should be used to end terrorism in the world and make it a safer place to leave. The countries should negotiate the border, land, water conflicts with peaceful talks rather than using military power that causes a lot of bloodshed. All of the mankind should lead a secure, peaceful life with the complete elimination of terrorism in this globe.
Having a big Military is absolutely one of the great assets of a nation, but in present geopolitical sphere, technology is emerging progressively important.
