Depending on depth it would be incredibly secure. Who is going to dive to 500ft to somehow hurt a big metal tube? How would you hurt it anyway, explosives? So we need an EOD diver/Navy seal who has extreme deepwater training, proper equipment and can find the damn thing. Yup, still secure. Also, what do you think nuclear proliferation means?
Nice troll though.

Here's the reality:
Spend as much as you can. People love it when you spend on new programs.
When the stupid people want you to cut spending cut to police and fire first so they will think twice about asking for cuts the next time.
Pay down debts?! Debts show your development! Every successful government is in debt. The more debt the more successful!
Always underestimate the cost of programs to make them look appealing, then overestimate the revenues from anything you do! It makes you look good!
