The US is making full usage of the bases in Europe to support Israel, without them it would have been logistically very hard; short of like the invasion of Afghanistan without the collaboration of Pakistan. These US bases fall under the US European Command (EUCOM) but are integrated into NATO’s architecture. The European NATO members, not only provide the bases, but subsidize the costs (e.g., infrastructure, utilities), therefore, becoming participants with the Israeli Campaign.

Countries can have some say. Spain, for instance, blocked some US airplanes destined to some campaigns, but it is just symbolic since the US just need not to declare the intention (or lie) and that is the end of the restrictions. It is not like Spain is going to inspect the vast amount of tonnage the US military is moving through Spanish ports, let alone between US bases. US could easily avoid the bases in Spain and use instead Germany, Italy and Morocco, but why would do so, when you can just humiliate your vassals in their face and have no repercussion at all... same as blowing up Nord Stream 2.

1. it is not true that every single county does that

For starters, every single member has diplomatic ties with the settler-colonial entity (save for Turkey's intermittent "severing ties" posturing), that alone is substantial material support. Now, I'm not going to list every single notable contribution to the settler-colonial entity for each member state in that organization, so please point out which member state does not contribute to the baby-and-women-murdering sex offender haven "state".

2. the ones that do, do it as individual states

NATO and Israel have worked together for almost 30 years, cooperating in domains such as science and technology, counter terrorism, civil preparedness, countering weapons of mass destruction and women, peace and security. Over the last year cooperation has grown, with NATO welcoming Israel’s intention to strengthen the naval interoperability by recognising Israel as a partner for NATO’s Operation Sea Guardian, and Israel’s Defence Force military medical academy now serving as a unique asset for NATO’s Partnership Training and Education Centres community.

And even if that was somehow true, which it isn't, it still doesn't change the fact that every single country in that T-word organization provides material support.
