The Democrats are providing military aide to Israel while trying to push a ceasefire and getting Hamas 100% on board with the terms

By pushing terms like 'the ceasefire is not permanent and we will continue to help Pissrael carry out the genocide against you'? Laughable.

Meanwhile, Trump thinks Israel is not genociding hard enough and needs to wipe out the Palestinians faster

The same applies to the USian Dems, so there's no difference here.

If we are talking strictly about voting, then you also have the options of not voting or voting third party. You don't lose anything by doing so, even, considering that both parts of your uniparty share the same policies.
