Infiltrating a walled town in the middle of a somewhat hostile wilderness >> walking into a church that prides itself on welcoming everyone. Infiltrating a town whose (somewhat xenophobic) population you do not look even remotely like is harder than infiltrating a church filled with members of your own race. Doing this, and then launching attacks without drawing any attention is also very hard.
The kobold's plan isn't impossible in the abstract (it is, perhaps, overly devious and might require knowledge the kobolds don't have), but it is almost certainly beyond their capacities. If they were lvl 10+, well, things might be different. If they reduce their plan to terrorizing outlying farms (which, themselves, are probably well defended if the world is to be self consistent), then things might work out for them (I would still expect a farm to be able to fight them off, a couple of guard dogs+a non-minion farmer or two is a minimal defense force).
You're presuming to tell me what is and is not possible IN MY CAMPAIGN with exactly 0 knowledge of the situation at hand. Hell, you know less about the situation than the players do. Take your bombastic pronouncements somewhere else please.
