[Phil V.]

1. The population harbors terrorists. They are terrorists. 
2. Natives? What are you talking about. Get a history book. 
3. Israel was attacked first from Lebanon, before it invaded.

. . . or you could say . . .

1. The corn field has weeds.  Corn is a weed.
2. Natives? YES! Get a history book.
3. Chickens and eggs.

1. The corn field has weeds. Corn is a weed.

Try this analogy, locust among grasshoppers.

The terrorists were generally of the same ethnic group as the locals. They were related by familial ties and lived amongst them. The natives hid terrorists.

Chickens and eggs.
Lebanon declared war on Israel in 1948. It never seeked peace with Israel. Terrorist attacks came from LEbanon, nt the other way around.
