After the first 12 hours, as chaos is setting in, release a video demanding that all heads of state sign an agreement to limit the wealth of legal entities worldwide, something similar to the existing agreement on minimum 15% tax for corporations. However, this is a wealth-based tax, not income based.

Set minimum limits, e.g.

1. No single individual may own or control more than 0.01% of the world's wealth (0.01% would currently equal around USD 40-50 billion).
2. No family may collectively own or control more than 0.05% of the world's wealth (think the Saudi Royal family).
3. Similarly no company's market capitalisation may exceed 0.05% of the world's wealth.

If their annual tax submission determines that they exceed those limits, they have 6-12 months to reduce their wealth. Companies can achieve this through splitting the company into smaller legal entities. Individuals may make charitable donations (anywhere in the world) but only to organisations that they can prove they and their family have no financial ties to. Also, the value of any non-profit organisations that they manage will count to wealth controlled by them/their families, to limit options for simply shuffling wealth around.

If they don't comply, the remainder is 100% taxable, with the tax collected globally based on the location of their wealth. I.e. if they have money sitting in 3 countries, each country can sieze their proportional share of the wealth in that country.

Any head of state that doesn't comply within 12 hours is added to the hit list. After the first few heads of state drop, the rest will comply quickly.
