Why we need a navy

[DelphiUniverse]

A navy is important because:

1. Over 70% of the earth surface is covered with water, you are going to need to use it someway or another
2. Transporting troops between nations that are separated with ocean
3. Some nations rely heavily in imported goods overseas and attacking these vessels is essential in long term warfare
4. Control of the seas means control of oil fields and other resources like fish, whales
5. Navies enable nations to launch air attacks that would normally be impossible without a navy
6. A navy can fight coastal defenses
7. A strong navy means that you are super mobile
8. A strong navy gives you abilities to interact and enable diplomatic chit-chat with pretty much any nation
9. No imperialism without a strong navy
10. A strong navy can fend off bigger battles to come in a single blow, preemptive attack
11. U-Boats is a stealthy instrument that can do lots of damage in the open sea, as we saw in world war 2, thousands of merchant vessels were lost
