Has the Trumpist Republican Party become a Front?

The Troubles and Trump

From 1968 to 1998 Northern Ireland was involved in a bloody conflict between Mostly Catholic, Irish Nationalists who wanted to join Northern Ireland with the rest of the Island and mostly Protestant Ulster Irish who wished to remain separate from Ireland & in Union with Britain.  Both sides used insurgency methods, though the Ulsterites had sometimes overt and sometimes covert support from Crown forces.

Sinn Féin and INLA

Most of the terror operations of the Northern Ireland Republicans were carried out by The Irish National Liberation Army (INLA, Irish: Arm Saoirse Náisiúnta na hÉireann).  This "army" was the terrorist "resistance" arm of the mostly Catholic Irish Republican Socialist Party or IRSP.

(Irish: Páirtí Poblachtach Sóisialach na hÉireann).

They separated from the larger Sinn Féin mostly to add a layer of legal separation from the earlier version of the Irish National Liberation Army, which had liberated Ireland from British Tyranny in prior years.

Violent Group Fronts

The Ulsterites fielded several "militia" which also employed a front, terrorist group operation. During that period politics in Northern Ireland became very ugly. It took intervention led by Irish Americans to settle "the troubles." 

The Broader Point

I'm referring to the troubles for a "broader point." You can look up insurgencies, they usually take that form. The front is an ostensibly peaceful group that poo-poos violence, but shares the otherwise violent aims of the terrorists. Front groups recruit, support, fund & excuse the terrorists & their deeds. Without them terrorists starve.

The Question

Have the Trumpist Republicans become a front group of Trumpist terrorism? Have groups like The Proud Boys or The Oathkeepers become shock troops for white supremacy terrorism?
