Perhaps. But consider that the Cold War went on for close to 50 years, and there are those who still consider the US to be the bad guy in that situation (or at least consider the US the moral equivalent of the USSR), even long after horror stories about communist Russia came pouring out.
I would seriously hope not, given the motivations of the Franco-German axis. Unless by “heroism” you mean “hypocritically self-interested stonewalling.” I would wager that, were peace to “prevail” in such a way as to bring about the demise of the Saddam regime and instill democracy in the country, it would be the US that would garner the credit, not Chirac and Schroeder, as they were opposed to us strong-arming Saddam to begin with - if they had their way, we’d still be ignoring Iraq’s lack of compliance with UNSC resolutions. If by “prevail” you mean that Saddam’s brutality is maintained, while his regime grows in power, then yeah, France and Germany would get all of the - ahem - credit.
