[5] Nahas has contributed to development in areas including policy formation and public administration in Syria, Jordan, Saudi Arabia and Iraq, amongst others.

[6] In 2006, Nahas wrote that "[a]lthough most of the rest of the world has moved on from the attitude that had been prevalent in the 1990s, according to which privatisation was the solution to all problems relating to public finance, Lebanon still adheres to that old mentality, either as a result of intellectual laziness or opportunism.

"[4] Subsequent reports indicate that Nahas supports the part-privatization of the telecom sector to a consortium of companies while ensuring that the government and the Lebanese public retains a stake.

During the summer of 2010, Nahas raised a number of objections in cabinet meetings to the draft budget law that was proposed by Finance Minister Raya Haffar al-Hassan.

In particular, he objected to what he described as the proposed law's failure to address Lebanon's basic economic difficulties (which manifested themselves in the form of high unemployment and emigration) at a time of relatively favorable circumstances (including a spectacular increase in capital in-flows since 2008).

Nahas proposed a number of changes to the draft budget law that would reduce the burdens on employment and on income, as well as increased investment in a modern public transport system in Lebanon.

[11] As minister of telecommunications, Nahas set as one of his goals to modernise the Lebanese telecom sector, which at the time was ranked as amongst the least competitive and the least developed in the world.

In his new position, Nahas focused on improving the rights of foreign domestic workers, on increasing the minimum wage in Lebanon and on granting health care to all Lebanese citizens.

[14] Nahas put together a reform package during the fall of 2011, which had as its objective to ensure periodic adjustment of wages, in accordance with the legislation that is already in force, to redistribute revenue from rentier to productive services (by increasing taxes on real estate transactions), and to reinvigorate the role of the unions.

That package was rejected by the Council of Ministries, a majority of which voted in favor of a plan put forward by Prime Minister Najib Mikati.

[19] In the 2018 Lebanese general election, Nahas ran for the catholic seat in Mount Lebanon II - Metn district but lost to the FPM candidate Edy Maalouf.

In the 2022 Lebanese general election, Nahas ran for the catholic seat in Beirut I - Achrafieh but lost to the FPM candidate Nicolas Sehnaoui.
