There is always the Iran Contra issue.
The Iran Contra affair is an example of the US supporting terrorists and does not show Iran in a negative fashion.
The 'Iran Contra' affair was the Regan administation illegally selling arms (missiles) to Iran in return for hostages, without the knowledge of congress (which had banned such sales).
Some of the money Iran paid to the US for the arms was used to supply 'terrorists' in Nicaragua(the 'Contra') with US arms, training and support (ie the US mined Nicaragua's harbours, preventing maritime trade).
The US was found guilty in the ICJ and fined in 1986.
The US refused to pay the fine and blocked any attempt Nicaragua maked to collect (until Nicaragua gave up).
