Coming off a coup that initiated a new loop in the roller coaster of Egypt's political scene, the country's future is up in the air -- and with it, the future of the entire region.
Christian Whiton, a former State Department senior adviser, calls Egypt's turmoil "the most titanic political contest of our era."
What could lie ahead? Here, CNN experts -- some of them on the ground in Egypt -- and analysts weigh in on a handful of possibilities:
Opposition consumed by infighting
Egyptians who packed Cairo's Tahrir Square to call for the ouster of President Mohamed Morsy -- a longtime leader of the Islamist Muslim Brotherhood -- had vastly different agendas. Some wanted a return to the days of ousted President Hosni Mubarak; others had supported Morsy and were disappointed by him.
Going forward, don't expect the factions to work together easily, says CNN's Ian Lee, who has covered the region for years. "Infighting is inherent in the opposition and one of the strengths of the Muslim Brotherhood is their cohesiveness. ... The opposition suffers from arrogance and ego. Each leader believes he is better than the others."
No single charismatic leader has risen to unite the opposition, Lee says. Meanwhile, the Brotherhood's unity could help it rise again.
The opposition could change in time, says Whiton, as secular liberals who oppose Islamist rule come together. "Ultimately, liberals do get organized, but it often takes time," he writes on CNN's GPS blog.
The question is how long the country has before Egyptians take to the streets en masse rejecting the military leadership -- like what happened after Mubarak was ousted in 2011.
If the military fails to draw a consensus and move the transition swiftly, it could face a revolt, says CNN producer Salma Abdelaziz in Cairo. If recent history repeats itself, the military will "crush dissent with brute force and you have the whole fiasco all over again."
Muslim Brotherhood pushed into 'confrontational posture'
There is "terrible tension and fear among some in Egypt today" that the Muslim Brotherhood "will be forced underground again and into its historic, confrontational posture with the Egyptian army," says Christiane Amanpour, CNN's chief international correspondent and anchor of Amanpour.
The country's chief Islamist movement certainly won't 'be driven into extinction," says CNN Senior International Correspondent Ben Wedeman, who has covered Egypt for years.
"Despite the fact that many people are fantasizing that this is the end of the Islamist movement," the country will continue to "have to deal with the Brotherhood either as a political movement or underground movement," he says.
Some Egyptians "want to see the Brotherhood crushed," Wedeman says. "It's been shoved into a corner but won't take it lying down."
That could spell armed protests by the Brotherhood and its supporters, he says.
CNN's Cairo-based international correspondent Reza Sayah adds, "Getting aggressive with the Muslim Brotherhood risks a violent backlash that could lead to further turmoil."
'Last nail in the coffin' for Arab Spring
If turmoil and violence reign in Egypt, the global effects could be dramatic.
"One of the great triumphs of the Arab Spring was that it showed Islamists who were prepared to come into the political process and accept the democratic path forward rather than the violent jihadi future that Osama bin Laden and al Qaeda were espousing," Amanpour says.
Morsy won a democratic election only to be deposed through non-democratic means.
"What are you going to tell Islamists: that democracy is for everybody except them?" Amanpour asks.
The coup "could well foretell an end of the fledgling democratic experiment in the most populous Arab country which, by overthrowing its long-term dictator just a couple years ago, had inspired democracy movements around the Arab world," says Mohammed Ayoob of the Institute for Social Policy and Understanding, in a column for CNN.
"If the Egyptian military is allowed to get away with this unconstitutional act it may spell the end of democracy in Egypt for a long time to come;" he says. "It will also be the last nail in the coffin of an Arab Spring already teetering on the edge of the grave with a bloody civil war raging in Syria, brutal suppression of democracy activists in Bahrain, and near-chaos in Libya and Yemen."
