It is unlikely that any single country will replace the USA as the world's police force. Instead, we are likely to see a shift towards a more multipolar world order where multiple countries, such as China, Russia, and the European Union, play a more significant role in maintaining global security and stability. International organizations like the United Nations may also take on a larger role in addressing global security challenges. **

Yes, the United States has a social security system in place. Social Security is a federal program that provides financial assistance to retired and disabled individuals, as well as survivors of deceased workers. Workers contribute to the Social Security system through payroll taxes, and in return, they are eligible to receive benefits when they retire or become disabled. Social Security is an important safety net for many Americans, providing financial stability during their retirement years. **

Yes, hackers can potentially access external data storage devices if they are able to gain unauthorized access to the device or the network it is connected to. This could be done through various means such as exploiting security vulnerabilities, using malware, or conducting phishing attacks to trick users into providing access. It is important for individuals and organizations to implement strong security measures such as encryption, access controls, and regular security updates to protect their external data storage devices from unauthorized access. **

The security measures in the USA include a combination of physical security, such as border control, airport security, and law enforcement agencies, as well as cybersecurity measures to protect against digital threats. The Department of Homeland Security plays a key role in coordinating these efforts, along with other federal, state, and local agencies. Additionally, the USA has implemented various counterterrorism measures, intelligence sharing agreements with other countries, and emergency response protocols to address potential security threats. Overall, the USA employs a multi-layered approach to security to protect its citizens and infrastructure. **

Air force security is most likely, as it is a specialized branch of the military that focuses on protecting air bases, aircraft, and personnel. Navy security and mountain infantry are also important, but air force security is more specific to the protection of air assets and installations. **

Air force security is most likely to be the correct answer. This is because air force security personnel are responsible for protecting air force bases, aircraft, and personnel, which are critical assets that require high levels of security. Mountain troops and navy security personnel have more specialized roles and are not as commonly associated with general security duties. **

A Trojan can access external storage media by disguising itself as a legitimate file or program and tricking the user into downloading it onto the external storage device. Once the Trojan is on the device, it can then access and manipulate the files stored on the external media. Additionally, Trojans can exploit vulnerabilities in the operating system or software to gain unauthorized access to external storage devices connected to the infected system. It is important to regularly update security software and be cautious when downloading files from the internet to prevent Trojans from accessing external storage media. **

A Trojan can access external storage devices by disguising itself as a legitimate file or program that the user unknowingly downloads onto their computer. Once the Trojan is executed, it can then scan for and access any connected external storage devices, such as USB drives or external hard drives. The Trojan can then copy, modify, or delete files on these devices without the user's knowledge or consent. It is important for users to be cautious when downloading files from unknown sources and to regularly scan their devices for malware to prevent Trojans from accessing external storage devices. **
