This understanding could also lead to the group isolating itself when struggles did break as with the Miners' Strike in the middle of the decade. At that time Miners Support Groups developed in all of Britain's major cities but the SWP chose in the first months of the strike not to join them, on the basis that they were inadequate to deliver the solidarity actions, such as mass picketing and solidarity strike action, which the SWP argued were the tactics needed for the Miners Strike to be concluded victoriously. Later this stance was reversed. Although the SWP continued to argue that the Miners' Strike could only be won if other sections of workers were able to provide solidarity actions, as was the case in a number of major disputes in the 1970s, its members continued to be active around the dispute which was considered doomed to failure without solidarity actions. The hit squads which appeared late in the strike were seen as symptomatic of the desperation and isolation of the more committed younger miners and were firmly disapproved of.
