Doesn't work with gas pipeline, especially not with undersea ones. They scale down terribly poorly, becoming incredibly expensive to build and operate per bcm/y if made thinner/"smaller" to have many of them for redundancy. Also too long, equally well attacked at any point, thus impossible to defend, and impossible to fix once attacked (saltwater getting inside -> pipes are wrecked after a few days, long before they can be sealed and drained).
That's true. We should depend less on things that are so vulnerable. LNG is partially a solution though - a liquefaction or regasification terminal is easier to protect, and defence of shipping at sea is a well-debugged thing since WWI.

When (presumably) the Royal Navy was in charge of it. Since WW2 it's been the US one that's handled it, but... Some pundits *cough*PeterZeihan*cough* have been saying for a while now that America is withdrawing from the role of World Police.
