When a people are threatend to be destroyed by an enemy there comes a point where they must do unto others before they do unto you. Case in point --- Iran.
So how many tears have you shed for the people the Jews slaughtered??Oh what sympathy you have for all those your people massacred off the face of the earth. You are a disgrace to all of civilized humanity.
Extermination is described in several of Judaism's Torah commandments.
Not to keep alive any individual of the seven Canaanite nations (Deut. 20:16)
To exterminate the seven Canaanite nations from the land of Israel (Deut. 20:17)
Always to remember what Amalek did (Deut. 25:17)
That the evil done to us by Amalek shall not be forgotten (Deut. 25:19)
To destroy the seed of Amalek (Deut. 25:19)
The extent of extermination is described in the commandment Deut 20:16-18 which orders the Israelites to "not leave alive anything that breathes completely destroy them " Several scholars have characterized the exterminations as genocide.
