Possible catches based on past statements and decision. They don’t have to materialize, but we need to be vigilant:

• The German government might just be lying. They don’t have to report on decisions which weapons or other military equipment are exported to whom until much later.
• The German government might make distinctions between weapons and other military equipment and rebrand that equipment as for civilian purposes. i.e. spare parts for military vehicles, radio equipment, personal armor…
• The German government might satisfy itself with a declaration by Israel, where the material would be used and then not ensuring it isn’t used in Gaza. We saw the same last year in September when arms exports worth a hundred million Euro were authorized after Israel sign a waiver that they promise not to use them in war-crimes.
• The German government might have coordinated with the US to ensure the gap is filled, or organized circumvention by selling through a third country.
• The German government might have coordinated with Israel that this is only temporary and in return will use this as a fig leave to continue blocking economic and diplomatic efforts to pressure Israel.

The decision by the government is not binding like a law. There is no immediate repercussions for breaking it. The only repercussions are outcry by the people and media and down the line hopefully prosecution in The Hague.
