Laws between countries are done with treaties.
Whether the New England colonies were legal or not is debatable, but clearly the treaties say we were not to cross the Appalachians, and we did anyway.
Then we were not to cross the Mississippi River, and we did anyway.
We claim we paid for the Louisiana Purchase and bought land from Spain, but the truth is all that land belonged to the natives, not France or Spain, and we stole it all illegally.
So Manifest Destiny was not only illegal, but was implemented through deliberate genocide of the natives, with things like deliberate smallpox infestations, and wiping out the buffalo.
The Monroe Doctrine was illegal and immoral since it actually meant the US enslaving South and Central America. We installed evil dictators in Nicaragua, Argentina, Brazil, Chile, Honduras, Haiti, Cuba, etc.
The Spanish American war was evil and illegal.
The USS Maine was not torpedoed, but faulty boilers just blew up.
As for Pearl Harbor, the "newer ships" were mostly aircraft carriers.
So then why were the carriers not allowed to dock at Pearl Harbor?
No economic embargo is ever legal or even remotely could ever be legal.
It is illegal to conduct deliberately starve civilians.
