The most obvious similarity would be that both Left-Communists and Trotskyists are 'Communists', not just in the broad sense of fighting for a classless society, but in the more narrow sense of adherence to the Bolshevik line on inter-Imperialist war, that Communists should not only not support the war, but that they should seek the defeat of their 'own' capitalist class, and generalise this defeatism into the defeat of the bourgeoisie everywhere. They should, to coin a phrase, seek the transformation of the world imperialist war into a revolutionary civil war. We are both Communist groups in the sense of supporting the 1917 Russian revolution as a step forward for the world working-class movement. And we are also both Communists in the sense of supporting the creation of seperate Communist parties outside and against the traditional social-democratic parties (As a point of fact, it was only thanks to the efforts of the Communist Left that the PCd'I was formed in 1921), and the unification of all these parties in the Communist International in 1919. Following from this, both groups adhere to the dictates of the CI's first congress such as Lenin's theses on bourgeois democracy and the dictatorship of the proletariat. After this however, the paths of the two tendencies diverge in some signficant respects. It's not as clear as a straightfoward split, as both Left-Communism and Trotskyism are divergent tendencies with no clear homogenous line on certain issues, but in general there are four areas of disagreement which can be pinpointed.
Both Left-Communists and Trotskyists of course agree with the replacement of parliamentary democracy with the dictatorship of the proletariat. Trotskyists say we should participate in elections in order to spread our message to people. In practice, of course, a lot of the time they end up standing on a reformist political platform rather than an openly Communist one. One of the most infamous examples being the 'Militant Labour' group which advocated the creation of socialism through an 'enabling act' passed in parliament by the British Labour party. The 'Trade Union and Socialist Coalition' which ran in the elections this year is also another good example. Left-Communists oppose participation for various reasons such as the fact that it's contradictory to, on the one hand, participate in parliamentary elections and, on the other hand, denounce elections as a farce. Getting people to vote for you in elections could easily spread the illusion of social change through parliament. In the German revolution of 1918-19 the workers' freely gave up the power of the Workers' and Soldiers' Councils in favour of a bourgeois republic at the behest of the German Social-Democratic Party. Years of attempts to gain influence in society through elections to the Reichstag had clearly had an impact. Participation in parliament also tends to override other forms of Communist activity and it becomes an all-encompassing goal for the Party to win elections at the expense of other forms of activity. In the worst cases you can end up with a complete subordination to bourgeois legality and a rejection of illegal tactics in order to win acceptance within the state-apparatus.
On the question of the Social-Democratic parties our positions are completely at odds. The Trotskyists regard these parties as 'workers' parties' because they can count on the votes of large sections of the working-class. We (Or at least I) would say that this ignores the difference between the class in itself and the class for itself. Historically the labour movement provided a good deal of support for the liberal party in England. It was one of the root causes of the dissolution of the IWMA. This doesn't mean that the liberal party was or is a 'workers' party'. A 'workers' party' in the sense which Marx and Engels use this term in the Communist Manifesto is one which is for the programme of the class for itself - the DotP and the destruction of bourgeois ideological hegemony. The question of 'unity' with the Social-Democratic and 'Labour' Parties is a non-question for us since they are simply not part of the same movement and haven't been since the great betrayal of 1914. In terms of fighting fascism, the response of the Left in Italy was to advocate a 'united front from below', the unity of workers' of all stripes on the ground level to defend themselves against the fascist bands, as opposed to the UF 'from above' advocated by Trotsky, which involved a political alliance between the Social-Democratic and Communist parties.
In terms of the national question there is also divergence. Most Left-Communists say that support for one part of the bourgeoisie against another is qualitatively different from supporting the bourgeoisie in it's struggle against feudal absolutism, the context in which Marx and Engels supported national movements. We emphasis the character of Imperialism as a world-system as opposed to a policy undertaken by individual nation-states and the impossibility of defeating Imperialism within the boundaries of capitalism. We call for the fraternisation of workers' across borders and united action by the working-class to bring war to a halt. Trotsky by contrast was for the unconditional defence of colonised nations against the colonial powers, even when such defence would tie the interests of the workers' to a collapsing bourgeois state. This point is not an absolute one within what has historically been known as Left-Communism. Bordiga was for the defence of purely national struggles in colonial nations, and the International Communist Party was apparently at the head of the Palestine solidarity movement in France in the 80's. But I think most Left-Communists today would disagree with Bordiga.
The trade union question is another point of dispute. Trotskyists are for struggling within even the most reactionary of trade-unions to win them round to Communist positions. Bordiga and the Bordigists also agreed with Trotsky on this point. Most Left-Communists believe that this is a pipe dream since the trade-unions are tied in with the state apparatus, and historically when workers' struggles have radicalised the workers have been found outside and against the unions. Our positions on the response vary. The International Communist Current says that Communists should not work in unions at all. The Internationalist Communist Tendency says that it is feasible for Communists to work in the unions and argue their positions but not to become members of the union apparatus. The Internationalist Communist Party, the Italian section of the ICT, apparently has a policy of creating workplace committees of PCInt members and sympathisers in opposition to the unions. Historically the Communist Workers' Party of Germany (KAPD) also had a similar stance, although it was the workers themselves that organised outside the unions in the Arbeiter-Unionen movement, and whose organised expression, the AAUD, affiliated with the KAPD.
