How can israel be an american ally , if an israeli private company was caught selling an oil tanker to Iran ?

The ofer brothers' sold an oil tanker to Iran , and now all americans hate israel and do not concider israel as an ally . Can israelis travel to the USA right now after the shocking discovery ? when the whole public wants to kill them ? Israel is not an american ally . Americans hate israel and hate it even more now , after they discovered it . The USA sanctioned the Ofer brothers' company BTW .
