A long time ally of the USA since the foundation of Israel. Biden continued support for Israel like every other president, including Trump. Biden has been critical of the excessive and inhumane military action. This has been reported. Biden even threatened to end aid unless the humanitairan situation was not recognized.
Yes, Biden and other nations cooperated in attacks against Islamic groups who have been attacking commercial shipping, and American installations.
Doubtful, as Biden has been exceptional in analysis in learning that Iran is not directly involved, and that it is proxy groups that Iran supports that will be targeted. The reason Iran is using proxies is because they don't want war.
Russia knows better. In fact one reason why no NATO nation sends national forces is to remain neutral. Giving aid is an indirect involvement that doesn't warrant direct reprisal.
