If you mean the "capital" city of an imaginary state, it might as well be Atlantis or any other mythic creation...

But if you mean "capital" in the financial sense, then it is the unlimited funding from Qatar,  Iran, hateful ideologues like George Soros, the UN and its devious agencies, the corrupt and corrupting PA, deceived, ignorant would-be "humanitarians" in the West, and many more disgusting sources of money for weapons, murderous incentives, brainwashing and basic, unmistakeable evil. Plenty of capital for that.
