VAT is how most countries that aren't the USA handle this problem. But even then, this isn't global taxation that the USA wants to implement uniquely, if something was made and sold outside of the USA, the USA would never have a chance to VAT it.
I honestly can't tell if you're being ironic/sarcastic here. If this is seriously what the US wants to do, no amount of domestic tax reform is going to achieve it. Military conquest would be the only option (at least for unilateral global taxation). Then 'domestic' tax reform afterwards.
