In my opinion, it is always good to be prepared. we are the best-trained military in the world, however good, modern or ultra-modern equipment is usually essential.
Just imagine what the 1st Gulf War would have been like had it not been for our PGMs or the M1 tank. We can owe our safety not only to the sacrifices of men and women in uniform, but to the intimidation and deterrent a weapon like the F-22 stealth fighter or the JSF provides
After WW2 we downsized tremendously, defence budget was slashed, training and vehicle
maintenance went out of the window.
Then came the Korean conflict, we were totally ill-prepared to take it on at that time.
The US deaths initially, were the direct result.
It is imperative to have a strong Military, History shows that.
