New Star Wars, Anti Nuclear Ballistic Missile Defence System

The question is.
Do we need an anti Ballistic missile defence system, which the united states government has proposed?
Will it make us much safer from Nuclear attack, by our enemies.
Let’s not bluff ourselves into thinking, that the world is now a safer place, with the cold war behind us. In fact in my opinion, it’s a much more dangerous place, we could be looking at being attacked by nuclear Ballistic missiles, within 10 years.
So what do you think we should do.
Should we say yes to this anti missile system, which has never been tested, and is still being developed.
Or should we say no, and carry on as we are, and await the inevitable.
Is it better to have a defensive system that might work, than nothing at all.
