Sam2 , Avram in MD and others: I’ll let others continue the arguments with HaKatan (although many of quotes are bogus) but allow to answer the so-called obtuseness that I am accused of and also Avram’s question.
The Rambam clearly indicates that a person-not yet know as the Melech Hamoshiach- will wage war to free the jews from their oppressors.That is BEFORE he is recognized as the melech Hamoshiach. As a matter of fact, one of the “simonim” (signs) that he is indeed the melech Hamoshiach is the fact that he will wage those wars and free us.
So, please pray tell me how anyone can wage war if the sholosh shevuos are applicable. For you to say that they will not apply in “jemos hamoshiach” is a paradoz,because how do we know that he is the Moshaich? After all, he is just transgressing the sholosh shevuos!
However, if the sholosh shevuos are not applicable , there is nothing wrong in a person waging war ( like Bar Kchba) and THEN, if he is successfull, we may call him Melech Hamoshaich. That is the logical explanation of the Rambam.
