Of course we will have to get our Dilithium Crystals from the Martians, because they won't let us drill in Alaska.

Have you evr read the Asimov story titled, "The Martian Way"?

The drive system of the day was a nuclear powered steam drive utilizing a reactor and a large tank of water. Earth was able to hold sway over the Martian colonies because Earth had all the water.
Until, the water started to run out. What the Martian people did was to mount one last, desperate mission to Saturn and carved out a huge piece of water ice from one of the rings and hauled it back to Mars orbit where they offered to sell it to the Earthers for an exhorbitant amout of money. Very funny little short story.
