America tried to remain neutral.  After arming merchant and passenger boats to try and deter Germany from attacking US vessels, and failing, America started to get agitated and wanted war.

The president at the time was re-elected solely on his promise to stay out of the war (for the most part), so was hesitant and joining.  Fortunately, British Intelligence sent us a decoded message from Germany to Mexico.

Since you are an utter fucking moron, I will tell you what it said, in short anyways. 

Join our fucked up war and you can have all your territories back that the US took from you.  Blah blah blah. 

That was not publicized until after Germany was relentlessly killing American Vessels and the country said, "Fuck the no war policy, lets spill their blood for once".

The rest is history, oh wait, what I said was history.  Get some education you limp dicked worthless piece of fucking shit.

God gave you a brain, I highly suggest you use it for more then sucking on empty whip cream air cans. 

the French wont need our help next time. 

If you are referring to a now-dead mid-europe dictator: He was an Austrian.

Get back on your dildo antir, noone cares about the shit dribbling out of your arse.

I know that. He was also elected Reichskanzler of Germany in 1933. That makes him a German.
A. Schwarzenegger was Austrian, now he's Governator. that makes him an American.

why would the French be proud of a first lady of italian heritage?

Bangability.

And that bitch be Bangable with a capital 'B'.  And she sounds like she's got a streak of the kink in her.

Bowchicawowow.

The effect of the war upon the United States will depend upon what American citizens say and do. Every man who really loves America will act and speak in the true spirit of neutrality, which is the spirit of impartiality and fairness and friendliness to all concerned. The spirit of the nation in this critical matter will be determined largely by what individuals and society and those gathered in public meetings do and say, upon what newspapers and magazines contain, upon what ministers utter in their pulpits, and men proclaim as their opinions upon the street

I venture, therefore, my fellow countrymen, to speak a solemn word of warning to you against that deepest, most subtle, most essential breach of neutrality which may spring out of partisanship, out of passionately taking sides.
The United States must be neutral in fact, as well as in name, during these days that are to try men's souls.  We must be impartial in thought, as well as action, must put a curb upon our sentiments, as well as upon every transaction that might be construed as a preference of one party to the struggle before another.

So, to answer your question, there are a lot of ties in Europe that would make it ok for a French President to have an Italian wife. The have boundaries that separate the countries, but in reality they are intertwined.
