If George Galloway were an American, and the SWP were an American party, I'm sure a lot of liberals and leftists would be rooting for the latter against the former, for a purely tactical purpose of protecting the Democratic Party from Galloway.
The SWP is in many ways like the Ligue Communiste Révolutionnaire, their differences on the question of Islam notwithstanding, but Britain's electoral system and political culture don't allow the SWP to do what the LCR and the Parti Communiste Français can do in France by going it alone, and on a slightly larger scale what the Nihon Kyosanto can do in Japan, what the Partito della Rifondazione Comunista can do in Italy, and what Die Linke can do in Germany, let alone what the Socialistische Partij in the Netherlands recently achieved. But even if it could, on its own or in coalition, it still wouldn't make a lot of difference for the rest of the world. Continental Europe, where the Left is stronger than in Japan, the UK, and the USA, is still as much part of the US-led multinational empire, as it has been for a long time .1
What does it make sense for us, leftists of the empire, to do to break global imperialist unity forged and reforged after World War II?
