The Change:Beyond the long military conflicts in Iraq and Afghanistan, 9/11 and later attacks caused big societal shifts. Eleven days after 9/11, President George W. Bush created theDepartment of Homeland SecurityThis agency aimed to boost the nation's defense against foreign threats.

The domestic airline industry nearly failed. This forced the industry to adoptwidespread changesto fees and security. Air travel became much harder for everyone. Many of these changes remain in place.Global security shifted too.9/11 started decades of global military conflict.

The Attack:On April 28, 1996, the Australian town ofPort ArthurTasmania became the site of a mass shooting. Martin Bryant killed 35 people and wounded 23 others.

He also carried a semi-automatic Daiwoo 12-gauge shotgun.

Bryant received 35 life sentences without parole.

The Change:Before the attack, Australia’s gun laws resembled those in the United States, letting many people buy guns under local rules. After the massacre, Australia completely changed its gun laws, restricting sales and banning many gun types. It took 12 days for the National Firearms Agreement to become law, bringing these new rules:

The National Firearm Registry is not yet done. Still, all Australian areas reconfirmed the NFA in 2017. Regulations do not stop gun violence completely, but as of this writing,only one mass shooting has occurred in Australia since.

Another group carried out a mass shooting and took hostages at an Eagles of Death Metal concert at the Bataclan theater.The Bataclan theater..

One hundred thirty-seven people died. Hundreds were hurt. The Islamic State claimed responsibility.

The Change:France declared a two-year state of emergency. This ended with a tougher anti-terrorism law.a tougher anti-terrorism lawPresident Emmanuel Macron signed the new legislation. It took parts of the state of emergency and made them law. This increased police power to search homes without warrants and limit the movement of radical religious groups.

The assassination of a schoolteacher in 2020.Following a depiction of the Prophet Mohammad, new legislation called the “Anti-Separatism” law followed. This law limited hate speech and added new protections for civil servants. Suspicious religious groups and non-governmental organizations got extra oversight.

The Attack:April 19, 1995.Timothy McVeigh.McVeigh parked a truck filled with explosives at the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma.

McVeigh received a lethal injection in 2001.His accomplice, Terry Nichols, received a life sentence without parole because the jury could not agree on the death penalty.He got 161 consecutive life sentences.He holds the record for one of the longest prison sentences ever imposed on a single person in the US.The longest prison sentences ever imposed on a single person in the US.The longest prison sentences ever imposed on a single person in the US.

The Change:The bombing changed how the US viewed domestic terror threats. The US had previously focused much of its anti-terrorism effort on foreign attackers. Congress passed the Antiterrorism and Effective Death Penalty Act of 1996.The Antiterrorism and Effective Death Penalty Act of 1996., limitinghabeas corpus.the Constitutional right of a detained person to appear in court to determine if their confinement is lawful) and other provisions within the country when faced with similar atrocities.

The attack killed 191 people and injured about 1,800.

The Moroccan Islamic Combat Group, linked to Al-Qaeda, planned the attack because of Spain's involvement in the 2003 US invasion of Iraq. Spain and other NATO allies backed the US action in Afghanistan under Article 5, but Spain's choice to engage in Iraq was not required by NATO agreements.This action was not popular.This happened because92% of Spaniards opposed it..

The Change:The bombings happened just three days before the election.The attack directly affected the results.The incumbent conservative Partido Popular, expected to win, lost to the Spanish Socialist Workers’ Party. Both sides blamed each other for the bombings and their handling, but Prime Minister José María Aznar lost the election.

Much of the Partido Popular's problem came from itsblame for the attack.blame on theEuskadi Ta Askatasuna (ETA), the Basque separatist group., the Basque separatist organization. The opposition claimed the PP avoided blaming an Islamist group for the attack, which would have hurt their role in the Iraq Invasion. History shows the Partido Popular sought exactly that.

This marks the deadliest terrorist attack in the United Kingdom in decades.

The Change:Almost right after the bombings,Prime Minister Tony Blair called for new laws.Parliament rushed these laws through. The goal was to add rules targeting the condoning or glorifying of terrorist attacks as unprotected speech. This caused claims the government traded democratic rules for more security, something that happens often after similar events in the West.Some changeschanged how MI5 handled intelligence, increasing sharing among agencies.

Also, a new effort started improving digital data collection for intelligence assessment to stop future homegrown terrorism across all three British intelligence agencies.

The nation’s border lacked security. Sri Lanka asked the United Nations and Japan for help securing the Colombo International Airport and its sea borders.Officials identified weaknesses that let the attack happen.
