The largest border of the State of Israel is the border with Jordan. Thank G-d, it has largely been a peaceful border for much of the last few decades. But it was not at all a quiet border in the past. Today also, the Jordan border may not be the scene of many battles. But it is indeed the scene of massive weapons smuggling from Iran. Jordan is not a difficult country to smuggle weapons into from the Iranian direction. But Israel must work much more to seal up the border and collect the weapons that have gotten in.
