Its too late for that now. America has created a mess and will now be responsible for cleaning up that mess (or eschewing responsibility when things don't go as easily as Trump thinks they will, which is probably more likely). There is already a huge power vacuum that is going to be filled with chaos, it is too late to just bring Maduro back since the damage has already been done.
It's important to note only the top of the pyramid was removed here - not the entire government. Most everything will continue as usual for quite some time, or forever.
Just like removing the President of the United States wouldn't mean the country descends into chaos.
It does send a very clear message to whoever becomes the top of the pyramid next, however.
