LOL what do you think will happen to those exterior columns when their interior bracing is removed and when the collapsed interior pushes them out of the vertical at the base? The loading of the first few to fail, would be transferred to the others, until as the internal collapse continues across the building there were simply no long enough intact columns to take the increased load and the remainder would fail almost simultaneously.
Heres a twoofer level experiment for you to do......support a pile of paving slabs on a square of empty coke cans. until they are support about half the weight required to crush them (you can find that out by experimentation).
Now start tapping in the sides of the cans one by one, in groups, even spaced or randomly.....what do you think will happen when you have tapped about half the cans?
Find out......and watch those fingers
