"The US runs the risk of losing Turkey as a whole. The entire Turkish public is against US policies that disregard Turkey's legitimate security demands. Threats, sanctions and bullying against Turkey will not work. It will only increase Turkey's resolve. But it will also further isolate the US in both Turkey and on the international scene," Kalin wrote.
He pointed out that Washington "has undermined confidence to itself as a reliable partner and ally."
"The Trump administration has already picked fights with Canada, Mexico, Cuba, China, Russia, NATO, Germany and other countries for mostly domestic reasons," Erdogan's spokesman wrote.
Earlier on Friday, The New York Times published an article by Erdogan himself. Turkish President Recep Tayyip Erdogan wrote that Ankara may seek new friends and allies if it does not see more respect and reciprocity in bilateral ties with Washington.
The Turkish president stressed that unilateral US actions against Turkey would "only serve to undermine American interests and security."
The US government recently imposed sanctions on Turkish ministers for not releasing a pastor who was jailed by Ankara for allegedly playing a role in the 2016 military coup. The previous month, pastor Andrew Brunson was released from a Turkish prison and placed under house arrest.
Turkish President Recep Tayyip Erdogan said on July 4 that Ankara might freeze the assets of top US justice and security officials in response to US sanctions against Turkish ministers.
