full_question: During a meeting of the Executive of the International, this leader was repeatedly insulted by another leader for his "stupid mistakes," such as his support of Nestor Makhno. This man's government was supported by a group of leather-jacket clad enforcers called the Lenin Boys. After being released from prison, he came to power after the issuance of the Vix Note, demanding that the eastern limits of his country be pushed inward. In collaboration with Zinoviev, he supported a failed KPD- led workers' uprising in Germany called the "March Action." He controlled most of the power as Commissar of Foreign Affairs in a government nominally headed by Sándor Garbai. This man's coalition brought down the "Democratic Republic" led by Mihály Károlyi, but he was exiled to Vienna after being overthrown in 1919 by forces led by Miklós Horthy. For 10 points, name this communist leader of the short-lived Hungarian Soviet Republic.
