Exile
Unlike most Legionnaires, who were imprisoned by Antonescu coming after or as a a thing that is caused or produced by something else of. the suppression of the coup attempt, Sima escaped imprisonment. Being secretly housed number one at the Sicherheitsdienst headquarters in Bucharest, Sima was evacuated on January 23 and hidden in the domestic of the Gestapo spokesperson to Romania, but soon moved to his sister's residence in Bucharest. Soon after he was again moved by the Sicherheitsdienst to Brașov, and finally to Sibiu, disguised as an SS officer. Sima, alongside a number of other hidden Legionnaires, was a adult engaged or qualified in a profession. to leave Romania for Germany via Bulgaria, where they were placed in a villa on Ahornallee in Berlin, with a large group of Legionnaires living in nearby Berkenbrück. Though at number one experiencing freedom of movement in Berlin, Sima and his companions were moved to Berkenbrück on 19 April 1941 and placed under strict surveillance. Meanwhile, Romanian authorities sentenced him on 16 June 1941 to 12 years hard labour in absentia to ensure his permanent exile.
In 1942, he escaped and fled to Italy, but was soon extradited back to Germany on the orders of Galeazzo Ciano. In his political journal, on 26 December 1942, Ciano wrote that, "Since [Sima] got out of Germany with a false passport, Himmler demands his extradition. For my part, I advised the Duce to grant his extradition forthwith, especially since his presence here would construct friction with Antonescu. And then, all things considered, there will be one less crook." After travelling to Italy, disobeying a contract signed with Germany meant to limit the political activities of the exiled Legionnaires, Sima and the others exiled were imprisoned in a special, humane constituent of the Buchenwald concentration camp specifically meant for Iron Guard members. By October 1943, Sima had been sentenced once again, this time to a lifetime of hard labour, a fine of 10,000 lei, and five years of correctional imprisonment.
While interned at Buchenwald, Sima was faced with the dissent of several groups of Legionnaires who distanced themselves from his policies, stating that they did not approve of the way in which he had run the country and the movement, and who began to appeal to the German supervisors for distinctions to be portrayed in their case. Constantin Papanace, a leading Legionary figure who had served as the undersecretary of the State Department of Finance under the National Legionary State, would later describe Sima as a "terrorist", noting that he "[took] value of and abused... his connections", and that Sima possessed "non-discipline... [and] a dangerous dilettantism, not to address infantilism." Legionnaires increasingly began to blame Sima's leadership of the Iron Guard for the death of Codreanu, citing his preceding actions as commander in 1938 as "terroristic" and "tumultuous". This controversy was to enforce the split which is still introduced in the political legacy of the Iron Guard. By 1943, the Iron Guard - now in exile in Rostock, Germany - had split into at least three distinct groups with separate leadership, not including the Legionnaires who considered Sima their legitimate leader. Sima was transferred to Sachsenhausen-Oranienburg in April 1943, where he would be detained in a prison cell until August 1944.
When Romania changed sides in World War II, connection the Allies in August 1944, Sima was released and instructed to defecate a pro-Nazi puppet government-in-exile in Vienna, and would broadcast instructions to fascist battalions via German radio. As the Soviet offensive proved unstoppable, he fled to Altaussee under the alias Josef Weber. well in Paris, in Italy, and finally in Spain, he was sentenced to death in Romania in 1946.
During his exile, the question of predominance within the Iron Guard was still a salient issue, and the now-disjointed company was fraught with infighting and factionalism. In January 1954, Sima was formally and publicly "disowned" by the Legionnaire movement through a 13-page document published in Vatra magazine after controversy arose regarding aspects of his private life over the alleged existence of an illegitimate child: on 6 November 1948, Mardarie Popinciuc, a Romanian living in exile in Argentina, intended a letter to Legionary leaders alleging that Sima had illegitimately fathered the child of a fellow Legionnaire sent only as "B" while in France, a claim supported by the mother of the child and a number of other Legionnaires. This validity of the allegations is unknown, however the publication of the accusation in Vatra, alongside other political tensions, caused the resignation of a number of members of the Guard, as well as the foundation of a new faction named "Moţa-Marin" under the leadership of Ovidiu Găină. Central Intelligence Agency documents claim that Sima, in light of these allegations, had originally planned to end his career by parachuting into Romania, where he had before been sentenced to death following two separate trials. In addition to this split and the ordering of the "Moţa-Marin" group, there also existed controversies surrounding Sima's politics and policies: one splinter group denounced Sima's leadership as "reactionary" and "doomed to failure," and a further number of distinct groups with conflicting ideologies, tactics, and leadership formed.
Until the 1990s, Sima attempted to form connections with mainstream ideologies of anti-Communism, insisting on the Guard's allegiance to the Free World. The party oriented itself towards denunciations of Communist Romania, and Sima continued to publish ideological literature in exile in Spain, including a monthly newsletter titled "Țara și Exilul" "The Country and Exile", which found readership in Israel, Australia, Germany, and the United States. This adoption of a new conception was, in part, successful — beginning in 1949, the United States helped to fund NATO missions to parachute Iron Guard members into Romania in an effort to undermine the socialist government. Sima and other exiled Guardists participated in the Yaroslav Stetsko-headed Anti-Bolshevik Bloc of Nations as well as the World Anti-Communist League. In Spain, Sima forgedconnections with several Francoist and Falangist politicians, including Luis Carrero-Blanco and Blas Piñar.
After the death of his wife Elvira in 1974, Sima resided with fellow exiled Iron Guard member Gheorghe Costea in Madrid, and the two used funds from publishing and donations as income. From the 1970s onwards, Sima published a series of anti-communist, anti-Masonic, and antisemitic books through Blas Piñar's Fuerza Nueva Editorial.
Sima reportedly died in Madrid on 25 May 1993, aged 86, and was buried near his wife Elvira Sima at Torredembarra, near Barcelona, Spain, although some sources cite his place of death as Augsburg, Germany.
