He was a senior research fellow at the Center for the Study of Terrorism at John Jay College, on the scientific advisory board of the Sigmund Freud Foundation in Vienna, and a member of the Seminar for Existential Psychoanalysis in Zurich.

He has developed this position further in Freud's Legacy in the Global Era (2016),[4] taking into account recent developments in cognitive neurosciences and contemporary existential psychology, and also argued that psychoanalysis needs to take into account the deep social and cultural changes, partially due to globalization, that shape today's patients' lives, a theme he has written extensively about in the last twenty years (see section below).

The self had become an endless experiment, and GenXers expected to have spectacular lives in which professional success needed to be combined with experimentation in the domains of sexuality, lifestyle and shaping the body almost at will.

Strenger's account combined individual case-studies with interpretations coming from a variety of disciplines like psychoanalysis, existential psychology, sociology and cultural criticism.

[14] In his The Fear of Insignificance: Searching for Meaning in the Twenty-first Century[15] Strenger argued that a new species he calls Homo Globalis, defined by its intimate connection to the global infotainment network, has emerged.

Using findings of existential psychology, Strenger argued that it was becoming progressively more difficult for Homo Globalis to maintain stable self-esteem, because every achievement is compared to the spectacular success stories publicized by the media.

He claimed that the development of modern Jewish Universalism provides an interesting paradigm for this identity, and has portrayed Sigmund Freud, Hannah Arendt, Isaiah Berlin,[23] Leo Strauss and Philip Roth[24] as examples.

In his Israel, Einführung in ein schwieriges Land (Suhrkamp 2011), he has argued that Jewish Universalist ethics is currently in conflict with dominant nationalist tendencies in Israeli politics.

Strenger was publicly involved in Israeli politics and culture from the late 1990s when he represented Israel's left in a weekly radio talk show,[28] in 2003 elections he was on the strategy team of the Labor party.

From 2007, Strenger was a columnist for Israel's leading liberal newspaper Haaretz,[31] and for Neue Zürcher Zeitung,[32] and wrote occasionally in Britain's The Guardian,[33]The New York Times and Foreign Policy and blogged on the Huffington Post.

[34] Strenger was a proponent of the two-state solution, i.e. he claims that the only way to end the Middle Eastern Conflict is establishing a Palestinian state with East Jerusalem as its capital alongside Israel.

[43] Strenger was an advocate of a liberal form of Zionism reaching back to Ahad Ha'am and has developed this vision in an essay entitled Knowledge-Nation Israel[44] and a number of opinion articles.

[48] Alongside numerous scientific papers, he was the author of eleven books on psychoanalysis, politics and liberalism, and individuality and meaning in a Global era, which were translated to various languages:
