An older ally...really? The enemy of my enemy is not necessarily my friend.
The French and English have been at each other's throats since the 12th century. If some clown tries to tell you how much the French cared for the colonists, read about the Massachusetts Deerfield Massacre of 1704. In truth the French used the American Revolution to continue their war against the British. They have only been "a friend" to the US (or anyone else for that matter) when it has suited their purposes.
An older ally? Debatable but certainly not the French.
Let's see, 1778 (to clarify, this was the year France began to help) minus 1704 makes 84. An incident generations before American independence disqualifies the French nation from being recognized for what it is, the longest-running friend of American democracy and ideals (many of which came directly from French philosophers)?
For you, readers, to decide.
Why did France wait until 1778 to side with the colonists? Saratoga was a battle fought in October, 1777. Americans won a significant victory against the British that gave everyone cause to believe that Americans could prevail and win against the British.
Up to that moment we had been begging the French for their help. Only when they thought we could win did they join the cause. They saw that we could provide them with a victory against their traditional enemy. Had we not won the battle, they would have probably told us "tant pis pour vous" - too bad for you.
If we look at our relationship with the French to the present day, it is extremely difficult to see anything that could equate to a real act of friendship on their part.
I am sure that anyone here can list at least a dozen instances of French arrogance. Doubt that the opposite is true.
