After the proclamation of the independence of Indonesia, he began to meet his people of his own and the younger generation. He also started to use his real name after 20 years using aliases. He then traveled to in Java and saw Surabaya people fighting against the British army in November. He realized the differences of struggling between the people in some places and the leaders in Jakarta. He thought the leaders were too weak in negotiation with the Dutch. Tan Malaka's solution to this perceived disconnect was to found the Persatuan Perjuangan (Struggle Front, or United Action), a coalition of about 140 smaller groups, notably not including the PKI. After a few months of discussion, the coalition was formally founded at a congress in Surakarta (Solo) in mid-January 1946. It adopted a "Minimum Program", which declared that only complete independence was acceptable, that government must obey the wishes of the people, and that foreign-owned plantations and industry should be nationalized. The Persatuan Perjuangan had widespread popular support, as well as support in the republican army, where General Sudirman was a strong supporter of the coalition Tan Malaka was organizing. In February 1946, the organization forced the temporary resignation of Prime Minister Sutan Sjahrir, a proponent of negotiation with the Dutch, and Sukarno consulted with Tan Malaka to seek his support. However, Tan Malaka was apparently unable to bridge political divisions within his coalition to transform it into actual political control, and Syahrir returned to lead Sukarno's cabinet.
