You're not getting it. Just like what happened during Breach Cinder may be able to make a few holes in the defense, but it'll be plugged up so quickly that the damage is negligible. Not to mention that if Vale is so weak that a few hundred foreign soldiers is enough to turn the tide they would've been overrun a long time ago.
