"G-d has made the wicked one for the day of evil".
Heaven needs Ahmadinejad to tell the Israelis how evil they are, & that if they don't mend their ways, they will be wiped out.
When Nasrallah says that the Israelis are "apes, pigs, dogs and monkeys", he is merely reflecting Heaven's view that the Israelis really are apes, pigs, dogs & monkeys!
cf When the Nazis said that the Jews are untermenschen (subhumans), they were merely opining Heaven's decree that the Jews had become imitative apes by aping the gentiles & dropping their observance of the Torah, and had lost their tzelem Elokim, and now appeared to the goyim as something less than human (as explained by the Netziv).
