It has been reported that it would cost 349 billion to reconstruct Ukraine as it was before. I heard that the U.S. possess around 300 billion in frozen Russian asset, and I was wondering if the U.S. had the legal means to use that fund "illegally" and use it to finance the reconstruction of Ukraine? Is there a legal precedent for doing something similar?

Answer: 
**Legal from what perspective?**

International law consists of the assumption that states are [sovereign](https://en.wikipedia.org/wiki/Westphalian_sovereignty), and negotiated or customary rules between them. Just which customary rules are established enough to be [jus cogens](https://en.wikipedia.org/wiki/Peremptory_norm), binding on all states, is not finally clear. The ability of one state to deposit money in another state and get it back is **not guaranteed**. On the other hand, historically theft on this scale might have been a [casus belli](https://en.wikipedia.org/wiki/Casus_belli).

But simply taking that money would be a grave breach of trust into the financial services of a country, unless most or all *other* nations agree that it is a very special case. Russia is [arguing internationally](https://tass.com/economy/1504031) that Western sanction policies are a threat to the rest of the world. The Western [filter bubble](https://en.wikipedia.org/wiki/Filter_bubble) tends to dismiss it as propaganda, but it has some succes in the rest of the world.

If the US takes Russian money, would China, Saudi Arabia, India, Brazil trust American banks? And if they *don't* trust them, can they find an alternative?

*Follow-up: as you can see from the comments which have since been removed, some readers seem to think that I share the Russian position. I do not. But I do believe that (too) much of the rest of the world shares it, and that the West needs to be careful not to play into Russian narratives. Global support for sanctions is* not *automatic, it takes effort to maintain it.*
**Yes**.

The only potential hurdle to it would be sovereign immunity. But **sovereign immunity can be removed with a legislation**. There are already laws which remove sovereign immunity to civil law suits.

The criteria for sovereign immunity are established in [Foreign Sovereign Immunities Act](https://en.wikipedia.org/wiki/Foreign_Sovereign_Immunities_Act). But the act can be amended to allow more situations in which law suits can occur. ***For example***, [JASTA](https://en.wikipedia.org/wiki/Justice_Against_Sponsors_of_Terrorism_Act) amends it to:

> 
> authorize federal courts to exercise subject matter jurisdiction over any foreign state's support for acts of international terrorism against a U.S. national or property regardless of whether such state is designated as a state sponsor of terrorism.
> 
> 
> 

Other amendments can be passed to create exceptions to allow law suits under some other sets of limited circumstances.
