JERUSALEM (AP) — Israeli Prime Minister Benjamin Netanyahu says his speech to the U.S. Congress offered a "practical alternative" to a possible Iranian nuclear deal and that lawmakers "better understand" why the deal is bad.

Netanyahu spoke upon landing in Israel on Wednesday, after President Barack Obama said the Israeli leader had offered no viable alternative to preventing Iran from getting nuclear weapons.

Netanyahu says his alternative would extend the breakout time for Iran to create a bomb, and would maintain sanctions until Tehran stops "its sponsorship of terrorism around the world, its aggression against its neighbors and its calls for Israel's destruction."

He says he received "very encouraging" responses from Democrats and Republicans, saying they "better understand why this deal is bad and what the right alternative to this deal is."
