Flying above the deck even over water can limit your line of com signal....not to mention radio silence is usually maintained during such operations.
Normal procedures for air traffic controllers is to try to reach the intruding aircraft to determine its intentions on published radio frequencies for that airspace and also the emergency frequency (121.50 VHF). Military aircraft also (and mostly) operate in UHF band and these frequencies are known as well by all. If no reply is heard from the aircraft and it doesn't seem to be in an emergency or following any lost com procedures then military actions can follow, all pilots are aware of this.

The White House sent a confidential "pre-notification" to lawmakers in April detailing a plan to sell weapons kits to Italy to arm up to six Reapers, reported the Wall Street Journal (via the New York Post) on May 29. Formal congressional notification could come as soon as this week, stated the newspaper. Pentagon Press Secretary George Little told reporters on May 29 that he couldn't "comment directly" on the topic, since "there's a formal notification process to Congress" that has to play out. "I will say more broadly that, when it comes to foreign military sales to Italy, that they're a strong partner and a strong ally" and "it's important for us, for a variety of reasons, to share technologies and capabilities with them," he said. Britain already operates armed US-supplied RPA.
Turkish Army denies WSJ report on jet downed by Syria
The Turkish General Staff gas denied claims by The Wall Street Journal that a Turkish jet shot down by Syria on June 22 was hit in Syrian air space.
The General Staff published a statement on its website July 1, giving detailed information on the plane's last known coordinates. "The plane was shot 13 miles off the Syrian coast, in international air space. The last coordinates at which the plane resumed controlled flight were 35 48.22 North, 35 33.21 East. From that point on, the plane quickly began to lose speed and altitude, crashing near 35 48.26 North, 35 37.59 East, within Syrian waters."
The statement said the plane was flying solo and unarmed in a mission to test radar systems.
Four of the six jets were scrambled from the air base of Incirlik in response to Syrian helicopters flying close to the Turkish province of Hatay, ******* quoted Sunday's army statement as saying.
Two more F-16s took off from a base in Batman after Syrian helicopters were spotted close to the province of Mardin, it added.
The military said the helicopters flew as close as four miles (6.5km) to the border, according to the AP news agency.
Not one or two, but six of them. They're not relaxed these days.
