When solidarity exists among members of a group based on ideology and that solidarity gives birth to their allegiance to each other and their allegiance against those who oppose them what verb and preposition collocates with it?
For example: 'The Nazis never (verb) solidarity (preposition) the allies: they were two opposing ideologies.'
A lot of the time 'show solidarity with' is used, but that is usually used to suggest that another group shows a temporary solidarity with another group that is bound permanently by solidarity.
So we might say, 'The British people showed solidarity with the victims of the Haiti earthquake.'
I want the collocation that is used to express the fundamental and permanent solidarity that is an integral part of being a member of a particular group/people/movement, etc.
