Aikido is a discipline and it is stated that there is no fighting in Aikido. Aikido has a little mentioned thing called ma ai. When faced by a person feigning to do this or that, boxing, kung fu, whatever, in other words when trying to be drawn into a fight the the discipline of Aikido says keep ma ai. Thus no fight.
Ma ai is by no means unique to aikido, or even to Japanese arts.
"Keeping ma ai" while waiting for an opening sounds like a good way to get yourself backed into an untenable situation, though.
