Under Donald Trump's peace plan for Gaza, the "yellow line" - which Israel withdrew to earlier this month - is the first of three stages of Israeli military withdrawal. It leaves it in control of about 53% of the Gaza Strip.
One Israeli newspaper, Yedioth Ahronoth, referred to it as "effectively the new border" in Gaza.
It's a remark that will please the far-right coalition partners of Prime Minister Benjamin Netanyahu.
The fortifications and demarcations Israel is now building along this boundary are meant to clearly divide the territory, but they may also help to blur the differing hopes and expectations of Mr Netanyahu's allies in Washington and at home.
How long he can keep both sets of expectations in play depends largely on this next stage of negotiations.
