If the Germans had not launched Barbarossa or delayed it until their next line of tanks came into service(while the Panther would not be the same, at the very least there would be Tigers) what would change with North Africa? How much further would the Germans get, seeing as they would have an extensive amount of men and material available that otherwise was preparing for Barbarossa? I know supply is an issue, but maybe with more Germans in North Africa there's more emphasis on solving this?
