Overthrowing a regime is far easier then building a new stable system. It’s far easier to protest and rebel against the rulers than build a stable prosperous state from scratch. In general, rebellions have caused more harm than good and we have seen rebellions consistently cause chaos throughout most of human history. It’s not a coincidence that most Islamic scholars throughout history were Anti-rebellion since the harms far outweighed any gains. Even if the ruler is a Kafir, it’s only permissible to remove him from power if the local Muslims have the ability to do so and it does not cause greater harm for that country/region. If the Muslims don’t have the ability or if removing him is going to result in greater harm than it’s not permissible to do so.
Al-Imām Ibn Taymiyyah (d. 728H) stated: “There have not been a people who revolted against their ruler except that their condition after their rebellion was worse than before they rebelled.” (Minhāj As-Sunnah 3/231)
In Tunisia, the people protested against their tyrant ruler. Now the country’s economic machine out of order, there’s zero growth, 16% of Tunisians don’t have jobs and youth unemployment is more than 34%.
In Egypt, the people protested against their tyrant ruler. The setbacks far outweighed the gains. The army exploited the situation to take power and replaced the countries system with a military dictatorship (after the Muslim brotherhood was ousted from power). Some say the current military regime is more brutal than it’s predecessors.
In Libya, the people rebelled and Qaddafi was captured and killed by the Libyan rebel militia. Qaddafi’s regime fell and the country collapsed into chaos. There’s 2 rival groups gunning each other down and there are multiple militia groups fighting one another.
In Syria, the people rebelled against Assad (and rightfully so but they were not organized), Assad massacred the people and the country collapsed into a chaotic civil war, which made the people into refugees and the chaotic environment enabled terrorist groups like ISIS, AQ etc to exploit the situation and terrorize the country even more.
In Iraq, when Saddam Hussein was removed from power, rebel groups filled the power vacuum, the country collapsed into chaos which allowed groups like ISIS to thrive. It also allowed Iran and other foreign powers to exploit the country for their own political agenda. The country has since not recovered.
