Should governments stop spending large amounts of money on their armed forces?

The world today is a safer place than it was a hundred years ago, and the governments should stop spending large amounts of money on their armed forces. To what extent do you agree or disagree with this statement? (IELTS writing, I am taking the IELTS on 5th May, so please help me review my work!)

The human species has gone through several stages of history. There were times of peace, development, and times of war, chaos. Such dreadful, traumatic events have all gone. As citizens of the 21st century, we are enjoying utmost safety and tranquility. However, governments of many nations still spend a staggering amount of money on their military forces and, from my perspective, it is an utter waste of resources.

First and foremost, there is a great number of contemporary matters that are urgently lacking due concern from governments. While war no longer poses great threat to us, other problems have arisen, ranging from natural disasters caused by climate change, people welfare to dangerous diseases. So severe are these problems that without timely actions, they can put human existence in jeopardy.

In addition to this, investing on the armed forces can increase the risk of war. International relations have recently been intensified as a result of illegal experimentation and mass production of new weapons. North Korea is a good case in point, as its governments has, for years, against international law, been developing life-threatening atomic weapons. Possibly, it is a means for nations to display their military power to the world, which actually does no good in ensuring a better life quality for their citizens.

By ways of conclusion, I once again reaffirm my position that it is absurd to spend large amounts of money on the armed forces in this time of peace. This money should instead be better spent on ameliorating life conditions and providing public services.
