True enough, but I believe and hope Jon is smart enough to focus on the White Walkers. The North is impossible to invade by land from the south, and so is the Vale. Unlike Robb, Jon has demonstrated several times that he's not lacking vision. As long as he doesn't do anything stupid, his position can only be threatened by the White Walkers. A smart man would stack up supplies in Winterfell and have a safe place to retreat to should everything go wrong.
