No Louisiana Purchase

This is my first attempt at posting and any critique is more than welcome. My biggest concern is if this scenario would be plausible had Jefferson decided against making the Louisiana Purchase due to constitutionality questions.

What If?

Jefferson decides not to make the Louisiana Purchase (Point of Divergence)

France still fights with Britain (Napoleonic Wars)

Jefferson still wants to expand west

America attacks French at New Orleans to control the important port city

America can actually help the British since both are fighting France

No war of 1812 between Britain and America (seems like a war that could have been avoided had there been a mutual interest in avoiding it)

Madison helps Brits defeat France by continuing assault on French in the New World and trade embargo

United States gets Louisiana Territory since Britain has little use for it

Manifest Destiny remains intact

It seems reasonable enough. America was equally pissed at Britain and France. If Britain was a bit more careful, there could have easily been a Franco-American War IOTL, even after the Louisiana Purchase,

I am not convinced that the massivily Pro-France and Anti-English Jefferson would ever attack French territory.

I could see an American force "helping" to re-inforce the French if England attacked Louisiana and then staying.

As far as I am concerned the US only started the 1812 war because Madison and the War Hawks thought that Napoleon would beat the English eventually (after having destroyed Russia), why would they want to take on the power that controlled the whole of Europe?

I think something to this extent is reasonable. If it looks like England might get Louisiana either through direct conquest or treaty the US is going to move to take New Orleans. Everyone was well aware that whoever controlled the mouth of the Mississippi controlled the fate of the continental interior and as the US expanded into the Mississippi and Ohio valleys their interest grew.

No matter what happens between England and France the US is going to take Louisiana either peacefully or not. There are far too many Americans pushing west and far too few French settlers in their way.

What if Jefferson doesn't get re-elected in 1804?
 
""on the globe one single spot, the possessor of which is our natural and habitual enemy. It is New Orleans, through which the produce of three-eighths of our territory must pass to market . . . the day France takes possession of New Orleans . . .[we will be forced to] marry ourselves to the British fleet and nation."-Thomas Jefferson to the Minister to France.

So, I think he'll go to war.
