“curb” is a bit of a stretch. They merely limited 30 of over 300 arms export licenceses. It is a start, but there is still a long way to go. And every day that goes by wihtout a clomete military and economic exclusion of all illegal israeli activities from its supporters, more people are murdered, more land is stolen, more homes are destroyed, with the complicity of Israels supporters.
The ICJ has concluded in its advisory opinion, that the occupation of Gaza, East jerusalem and the Westbank are all illegal and must end. It is complicity in crime to support these illegal occupations in any way, including by engaging economically with the occupation.
