The FBI has already been doing this, Congress authorized the FBI to conduct all of the state sponsored hacking. It was just a little complicated.
No US law applies outside the US (or US flagged ships etc).
The USA might like this to apply, but that doesn't make it true.
Typically regarding raids and property seizures they collaborate with local authorities in foreign countries, with one FBI agent present to make sure the raid is compliant with US laws.
Sometimes such compliance violates the local laws, and merely delays extradition proceedings. But the US typically gets the result it wants by freezing the property and preventing the person from continuing their behavior, and if they get the person to the US for jail and trial that is just icing on the cake.
"no" is a bit strong there.

> Federal law provides “extraterritorial jurisdiction” over certain sex offenses against children. Extraterritorial jurisdiction is the legal authority of the United States to prosecute criminal conduct that took place outside its borders.
Its okay, everyone believes what you believe, this isn't reality though.
although the FBI is a domestic enforcement agency, Congress specifically gave it the ability to hack any computer anywhere in the world.
Despite whatever concepts you have ever heard about any agency's mission or limitations, Congress has the ability to delegate tasks to whatever agency it thinks have resources, and then those laws stay on the books.
