Well given that it's the natural barriers that protect the four current kingdoms today, no. The grimm outnumber man immensely,  and the only reason humanity has been able to keep them at bay this long and maintain their borders is soley because of the natural barriers. Mountain glenn is a prime example of what happens to a society that is unguarded by nature's womb. That, and past civilizations that have succumbed to ruin. So, while the military may be mighty, even they won't be able to conquer the grimm. Not ye5 anyway. Not individually. I think each kingdom should gather their military or hunts force and go on a quest to exterminate each and every last grimm on planet remnant.
