I think that the goverments don't have to elimate the army. THe army is an important group of people taht could save our life while they are sacrificing themselves.
And what will happen if another country attacks us?
They army of other countries would exterminate us if we don't have an army.
These are the reasons why we are using an army.
Then, another example:
Afew months ago, the people that control the airports, went on strike, in the middle of the Easter Hollydays. Then the army appeared and solved the prolem.
In conclusion, I'm in favor of this opinion. The reasons yo eliminate the army are less strong than the resaon to preserve it.
