This month the US state of Texas approved a ban on all contracts with Airbnb, arguing that the online company's action was "antisemitic".
As both sides understand, a lot hangs on the blacklist being made public.
If Israel and the US succeed, and western corporations are left free to ignore the Palestinians' dispossession and suffering, the settlements will sink their roots even deeper into the West Bank. Israel's occupation will become ever more irreversible, and the prospect of a Palestinian state ever more distant.
A 2013 report on the ties between big business and the settlements noted the impact on the rights of Palestinians was "pervasive and devastating".
Sadly, the UN leadership's cowardice on what should be a straightforward matter the settlements violate international law, and firms should not assist in such criminal enterprises is part of a pattern.
Repeatedly, Israel has exerted great pressure on the UN to keep its army off a "shame list" of serious violators of children's rights. Israel even avoided a listing in 2015 following its 50-day attack on Gaza the previous year, which left more than 500 Palestinian children dead. Dozens of armies and militias are named each year.
The Hague court has also been dragging its feet for years over whether to open a proper war crimes investigation into Israel's actions in Gaza, as well as the settlements.
The battle to hold Israel to account is likely to rage again this year, after the publication last month of a damning report by UN legal experts into the killing of Palestinian protesters at Gaza's perimeter fence by Israeli snipers.
Conditions for Gaza's two million Palestinians have grown dire since Israel imposed a blockade, preventing movement of goods and people, more than a decade ago.
The UN report found that nearly all of those killed by the snipers 154 out of 183 were unarmed. Some 35 Palestinian children were among the dead, and of the 6,000 wounded more than 900 were minors. Other casualties included journalists, medical personnel and people with disabilities.
The legal experts concluded that there was evidence of war crimes. Any identifiable commanders and snipers, it added, should face arrest if they visited UN member states.
Israel's prime minister Benjamin Netanyahu, however, dismissed the report as "lies" born out of "an obsessive hatred of Israel".
Certainly, it has caused few ripples in western capitals. Britain's opposition leader Jeremy Corbyn was a lone voice in calling for an arms embargo on Israel in response.
It is this Israeli exceptionalism that is so striking. The more violent Israel becomes towards the Palestinians and the more intransigent in rejecting peace, the less pressure is exerted upon it.
Not only does Israel continue to enjoy generous financial, military and diplomatic support from the US and Europe, both are working ever harder to silence criticisms of its actions by their own citizens.
As the international boycott, divestment and sanctions movement grows larger, western capitals have casually thrown aside commitments to free speech in a bid to crush it.
