Trump knows bombing Iran's Fordo nuke site has pros and cons.  
He thinks it's needed 'cause weapons could be made fast there.  
"Not many options," a source says. "Destroying Fordo gets it done."  
Trump okayed an attack plan but hasn't decided yet.  
He'd let the US join strikes if needed to take Fordo out.  
By Thursday, he was still weighing choices.  
One idea: Iran could shut Fordo down itself.  
But no final call's been made.

Wow Trump is really thinking hard about Fordo, balancing the risks and rewards like a boss, hope he makes the best call for everyone
