What others are saying about the job market for history in academia is right. Although an MA is what's required to teach history at a community college, there is such a glut of PhDs in this field that in general, you won't get a job as a full time history teacher at a community college without a PhD. And depending on what's going on in your region re: available labor, you may also not be hired as an adjunct with just an MA.
Getting a tenure track job with a PhD in history at a university is not promising. You need to make this choice with your eyes open to the reality of this job market. And it wasn't good even before the recession - now it's awful.
Others have mentioned the specific classes you can take to get yourself a reading level of French or German. Seriously, do not discount this idea, if it means you can apply to more programs. Here is one example of such a graduate reading course, so you know what you're looking for:
Again, you are not looking to become fluent in the language. You are looking to pass the reading exam. You say you already speak some French, so I bet you could perhaps try to get the appropriate reading level in that language, and get there fairly quickly. Check the unis around you to see if any offer such a class - a graduate reading course in French.
