Itachi never tried to kill Obito directly, they had a deal(something you seem to forget). Also if Torune and Foo could figure out how Kamui's intangibility works then Minato isn't special there, like at all... Those two only lacked the FTG and speed to handle it, Itachi doesn't as he is faster than Obito, Foo and Torune easily. If they never had the deal then I'm sure Itachi would of killed Obito soon after joining Akatsuki.
